| CVE-2026-15315 | 1 Tp-link | 5 Tapo C120, Tapo C120 Firmware, Tapo C200 and 2 more | 2026-09-04 | 8.8 High |
| Tapo C120 v1 and C200 v5 contain an improper authentication vulnerability within the login authentication verification module. An attacker on the local network can exploit weaknesses in challenge parameter validation to bypass normal authentication controls and obtain administrative session tokens. Successful exploitation may allow an attacker to subsequently execute privileged management actions, enable unauthorized administrative access and temporary disruption of device services, resulting in a denial-of-service (DoS) condition. | ||||
| CVE-2026-82538 | 1 Ilias | 1 Ilias | 2026-09-04 | 8.8 High |
| ILIAS before versions 9.22, 10.10, and 11.3 contains a SQL injection vulnerability in the repository trash table where the table navigation sort field from HTTP requests is passed directly into the ORDER BY clause of a SQL query without validation against declared sortable columns. Authenticated users with write permission on any container can inject arbitrary SQL through the sort parameter, and because multi-statement execution is enabled in the database layer, stacked queries enable full database read and write access as well as administrator account takeover. | ||||
| CVE-2026-85656 | 1 Amazon | 1 Log4j-cve-2021-44228-hotpatch | 2026-09-04 | 7.8 High |
| An OS command injection issue in the log4j-cve-2021-44228-hotpatch package in Amazon Linux before 1.3-9 might allow a local user to execute arbitrary commands with root privileges via a Java process whose executable path contains embedded newline characters. | ||||
| CVE-2026-82877 | 2 Ilias, Ilias-elearning E.v. | 2 Ilias, Ilias | 2026-09-04 | 6.5 Medium |
| ILIAS before versions 9.22, 10.10, and 11.3 contains an arbitrary file read vulnerability in the SOAP addFile method that allows authenticated users to read server files by supplying crafted XML with COPY-mode imports. Attackers can construct absolute file paths through an unsandboxed import directory and retrieve sensitive files including configuration files containing database credentials and setup passwords. | ||||
| CVE-2026-80759 | 1 Linux | 1 Linux Kernel | 2026-09-04 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_aml: validate firmware segment lengths aml_download_firmware() reads two lengths from the firmware header and uses them to build pointers before checking that the header and segment data are present. A truncated or inconsistent firmware image can make the driver read past firmware->data while constructing TCI commands. Reject images shorter than the header and ensure that the ICCM and DCCM ranges fit within the loaded firmware before downloading either segment. | ||||
| CVE-2026-80766 | 1 Linux | 1 Linux Kernel | 2026-09-04 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: HID: uclogic: fix use-after-free of inrange_timer on remove uclogic_remove() cancels the pen in-range timer and then stops the device: timer_delete_sync(&drvdata->inrange_timer); hid_hw_stop(hdev); timer_delete_sync() only guarantees the timer is idle at that instant. uclogic_raw_event_pen() keeps delivering pen reports until hid_hw_stop() stops the transport several lines later, and every report with pen->inrange == UCLOGIC_PARAMS_PEN_INRANGE_NONE re-arms the timer: mod_timer(&drvdata->inrange_timer, jiffies + msecs_to_jiffies(100)); A report landing between the timer_delete_sync() call and the transport teardown in hid_hw_stop() re-arms inrange_timer after it was cancelled. uclogic_remove() then returns and the devm drvdata is freed, while hid_hw_stop() has already freed the input device drvdata->pen_input points at, so when the timer fires ~100 ms later uclogic_inrange_timeout() dereferences freed memory -- a use-after-free in timer-softirq context. Swapping the two calls is not a fix: stopping the device first frees drvdata->pen_input via hidinput_disconnect() while the timer may still be pending, so a timer already armed before removal fires on the freed input device in the window before timer_delete_sync() runs. Use timer_shutdown_sync() before hid_hw_stop() instead. It cancels the timer, waits for a running callback while pen_input is still valid, and prevents any further re-arming -- a later mod_timer() from an in-flight report is silently ignored -- so the timer is provably dead before hid_hw_stop() frees the inputs. This is the ordering the timer core documents for this "timer re-armed from another path" teardown case. | ||||
| CVE-2026-80767 | 1 Linux | 1 Linux Kernel | 2026-09-04 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: HID: sensor: custom: Fix use-after-free in enable_sensor enable_sensor_store() can call set_power_report_state(), which dereferences sensor_inst->power_state and sensor_inst->report_state. These pointers refer to entries in sensor_inst->fields. Create the field attributes before exposing the enable_sensor sysfs attribute, so enable_sensor cannot be accessed before the state it depends on has been initialized. On remove, delete enable_sensor before freeing the field attributes, so a concurrent sysfs write cannot dereference freed memory through power_state or report_state. | ||||
| CVE-2026-80811 | 1 Linux | 1 Linux Kernel | 2026-09-04 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: io_uring/cmd: fix iovec leak when the async cmd is not recycled An io_async_cmd carries an iovec array in ->vec.iovec, allocated when the vec has to grow and kept across recycling through ctx->cmd_cache. On two paths nothing frees it and io_clean_op()'s kfree(req->async_data) drops the io_async_cmd without it. io_req_uring_cleanup() clears the async data flags only when io_alloc_cache_put() succeeds, and the cache holds IO_ALLOC_CACHE_MAX == 128 entries, so once it is full the put fails and the vec is left behind. An NVMe passthrough workload gets there without doing anything unusual: nvme_uring_cmd_io() returns -EIOCBQUEUED, so the io_async_cmd stays attached for the lifetime of the command and the live object count tracks the queue depth. Above 128 the puts start failing. ->cleanup is the last chance to free an inherited vec, since io_req_uring_cleanup() returns early for an io-wq issued command and is not called at all for one completed without ever being issued. But io_clean_op() calls ->cleanup only if REQ_F_NEED_CLEANUP is set, and for uring_cmd that happens only where the vec has to grow, so a command reusing a large enough cached vec never sets it. io_rw_alloc_async() and io_msg_alloc_async() flag an inherited vec for exactly this reason; io_uring_cmd_prep() does not. Flag an inherited vec in io_uring_cmd_prep(), and free the vec when the cache put fails, as io_req_rw_cleanup() does. The leak is invisible under KASAN, where io_alloc_cache_vec_kasan() frees the vec unconditionally. | ||||
| CVE-2026-80812 | 1 Linux | 1 Linux Kernel | 2026-09-04 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ALSA: dummy: Check card index validity at probe snd_dummy_probe() blindly trusts that the given devptr->id value is within the proper card index range. It's OK for the devices the driver itself creates at the module probe time, but if the device is bound manually via sysfs interface, this could be -1 as "none", and this leads to OOB access for index[] and other parameters. Add a sanity check for the card index and warn/correct it if it's a value out of the range. | ||||
| CVE-2026-80814 | 1 Linux | 1 Linux Kernel | 2026-09-04 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: rndis_host: add overflow check in rndis_rx_fixup() Add an overflow check to ensure that data_offset + data_len + 8 does not wrap, which would enable an OOB read of the USB data buffer. | ||||
| CVE-2026-80815 | 1 Linux | 1 Linux Kernel | 2026-09-04 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ALSA: scarlett2: Use a private URB for the notification endpoint scarlett2_init_notify() used mixer->urb, which snd_usb_mixer_status_create() allocates for the UAC2 status interrupt endpoint and mixer.c manages. On a device with that endpoint, the "already in use" check fires on the status URB and returns 0 for success without doing anything. No notification URB is submitted, and cmd_done is left zeroed because it is initialised past that check and nowhere else. scarlett2_usb_init() then issues SCARLETT2_USB_INIT_1 and wait_for_completion_timeout() would crash adding to the zeroed wait.head. Use a separate URB in scarlett2_data, as done for FCP, and initialise cmd_done in scarlett2_init_private(). mixer.c was also freeing the URB in snd_usb_mixer_free() and resubmitting it in snd_usb_mixer_activate(), so scarlett2 must now do both: add scarlett2_cleanup_urb(), called from private_free and private_suspend, and a private_resume callback to re-establish the URB after resume. scarlett2_init_notify() is reached from there, and the URB kill path in scarlett2_notify() completes cmd_done, leaving a stale count that would satisfy the next command's wait before the device ACKs. Use reinit_completion() to clear it. Also free the URB if the transfer buffer allocation fails, and both if usb_submit_urb() fails. Move scarlett2_init_notify() up next to scarlett2_cleanup_urb() so scarlett2_init_private() can reference it without a forward declaration. | ||||
| CVE-2026-80816 | 1 Linux | 1 Linux Kernel | 2026-09-04 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ALSA: FCP: Use a private URB for the notification endpoint fcp_init_notify() used mixer->urb, which snd_usb_mixer_status_create() allocates for the optional UAC2 status interrupt endpoint and mixer.c kills, resubmits and frees. On a device with that endpoint, fcp_init_notify()'s "already set up" early return fires on the status URB and returns success without doing anything. No FCP notification URB is submitted, and cmd_done is left zeroed because it is initialised past that early return and nowhere else. fcp_init() then issues init1_opcode and wait_for_completion_timeout() would crash adding to the zeroed wait.head. fcp_cleanup_urb() would also kill and free mixer.c's status URB. Use a separate URB in fcp_data, and initialise cmd_done in fcp_init_private() where fcp_data is allocated. fcp_init_notify() is reached again after suspend via fcp_reinit(), and the URB kill path in fcp_notify() completes cmd_done, leaving a stale count that would satisfy the next command's wait before the device ACKs. Use reinit_completion() to clear it. | ||||
| CVE-2026-80817 | 1 Linux | 1 Linux Kernel | 2026-09-04 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: iommu/iommufd: Fix NULL pointer deref in iommufd_ioas_change_process when racing with iopt_map_file_pages iommufd_ioas_change_process() iterates every IOAS area while only holding every IOAS iova_rwsem, so it assumes every area has a non-NULL pages pointer. That assumption can be false when it runs concurrently with iopt_map_file_pages(). iopt_map_pages() executes in two phases. It first creates the area and inserts it into the interval tree under iova_rwsem, with area->pages still NULL. It then drops iova_rwsem and later fills area->pages under domains_rwsem. This leaves a window between area creation and area->pages fill where a concurrent iommufd_ioas_change_process() can observe the area and dereference a NULL area->pages pointer, leading to a NULL pointer dereference: BUG: kernel NULL pointer dereference, address: 00000000000000c0 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 4b655067 P4D 4b655067 PUD 0 Oops: Oops: 0000 [#1] SMP NOPTI CPU: 0 UID: 0 PID: 11841 Comm: syz.1.628 Not tainted 7.1.0 #3 PREEMPT(full) Hardware name: QEMU Ubuntu 24.04 PC v2 (i440FX + PIIX, arch_caps fix, 1996), BIOS 1.16.3-debian-1.16.3-2 04/01/2014 RIP: 0010:iommufd_ioas_change_process+0x419/0xd50 drivers/iommu/iommufd/ioas.c:538 Code: 48 89 c3 48 85 c0 0f 84 cc 00 00 00 e8 10 f5 cb fd 48 8d 7b 68 e8 a7 b5 eb fd 48 8b 6b 68 48 8d bd c0 00 00 00 e8 17 b2 eb fd <8b> ad c0 00 00 00 bf 01 00 00 00 89 ee e8 85 ef cb fd 83 fd 01 74 RSP: 0018:ffffc90015c17d28 EFLAGS: 00010246 RAX: ffff8880186d5328 RBX: ffff88801d25e240 RCX: 0000000080000000 RDX: 00000000000002d7 RSI: ffffffff83ba9e10 RDI: 00000000000000c0 RBP: 0000000000000000 R08: ffffffff8e781eb8 R09: 0000000000000000 R10: 00000000000000c0 R11: ffffffff83ba9e29 R12: ffff88802e216008 R13: ffff88802e216000 R14: 0000000000000001 R15: 0000000000000000 FS: 00007f4aea3f66c0(0000) GS:ffff8880b1fa1000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00000000000000c0 CR3: 000000004b75c000 CR4: 0000000000350ef0 Call Trace: <TASK> iommufd_fops_ioctl+0x287/0x400 drivers/iommu/iommufd/main.c:533 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:597 [inline] __se_sys_ioctl fs/ioctl.c:583 [inline] __x64_sys_ioctl+0x120/0x170 fs/ioctl.c:583 x64_sys_call+0x1092/0x1fb0 arch/x86/include/generated/asm/syscalls_64.h:17 do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline] do_syscall_64+0x10a/0x680 arch/x86/entry/syscall_64.c:94 entry_SYSCALL_64_after_hwframe+0x77/0x7f RIP: 0033:0x7f4aec1a82bd Code: ff c3 66 2e 0f 1f 84 00 00 00 00 00 90 f3 0f 1e fa 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 b0 ff ff ff f7 d8 64 89 01 48 RSP: 002b:00007f4aea3f6018 EFLAGS: 00000246 ORIG_RAX: 0000000000000010 RAX: ffffffffffffffda RBX: 00007f4aec436090 RCX: 00007f4aec1a82bd RDX: 0000200000000180 RSI: 0000000000003b92 RDI: 0000000000000003 RBP: 00007f4aec250295 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000000 R13: 00007f4aec436128 R14: 00007f4aec436090 R15: 00007ffd04ef23e0 </TASK> Modules linked in: CR2: 00000000000000c0 ---[ end trace 0000000000000000 ]--- RIP: 0010:iommufd_ioas_change_process+0x419/0xd50 drivers/iommu/iommufd/ioas.c:538 Code: 48 89 c3 48 85 c0 0f 84 cc 00 00 00 e8 10 f5 cb fd 48 8d 7b 68 e8 a7 b5 eb fd 48 8b 6b 68 48 8d bd c0 00 00 00 e8 17 b2 eb fd <8b> ad c0 00 00 00 bf 01 00 00 00 89 ee e8 85 ef cb fd 83 fd 01 74 RSP: 0018:ffffc90015c17d28 EFLAGS: 00010246 RAX: ffff8880186d5328 RBX: ffff88801d25e240 RCX: 0000000080000000 RDX: 00000000000002d7 RSI: ffffffff83ba9e10 RDI: 00000000000000c0 RBP: 0000000000000000 R08: ffffffff8e781eb8 R09: 0000000000000000 R10: 00000000000000c0 R11: ffffffff83ba9e29 R12: ffff88802e216008 R13: ffff88802e216000 R14: 0000000000000001 R15: 0000000000000000 FS: 00007f4aea3f66c0(000 ---truncated--- | ||||
| CVE-2026-80819 | 1 Linux | 1 Linux Kernel | 2026-09-04 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: take rfcomm_mutex for the deferred setup accept rfcomm_sock_recvmsg() completes a deferred setup by calling rfcomm_dlc_accept() without holding any RFCOMM lock: if (test_and_clear_bit(RFCOMM_DEFER_SETUP, &d->flags)) { rfcomm_dlc_accept(d); return 0; } and rfcomm_dlc_accept() dereferences the session on its first line: struct sock *sk = d->session->sock->sk; Every other path that touches d->session runs under rfcomm_mutex: rfcomm_dlc_open(), rfcomm_dlc_close(), rfcomm_dlc_exists(), rfcomm_dlc_send_rpn(), and the RFCOMM thread through rfcomm_process_sessions(). rfcomm_connect_ind() is even documented as "called under rfcomm_lock()". This call site is the only one that skips it. The RFCOMM_DEFER_SETUP bit looks like it serialises the accept against teardown, since __rfcomm_dlc_close() returns early when it wins the test_and_clear. But rfcomm_recv_disc() forces the state first: d->state = BT_CLOSED; __rfcomm_dlc_close(d, err); and the early return only covers BT_CONNECT, BT_CONFIG, BT_OPEN and BT_CONNECT2. With the state already BT_CLOSED that switch does not match, the bit is never consulted, and __rfcomm_dlc_close() falls through to rfcomm_dlc_unlink(), which sets d->session = NULL. So a remote DISC on a deferred dlc clears the session while leaving RFCOMM_DEFER_SETUP set. The next recvmsg() then passes the test_and_clear and dereferences a NULL session. No timing window is needed: once the DISC has been processed, the dereference is unconditional. Give rfcomm_dlc_accept() the same shape as rfcomm_dlc_open() and rfcomm_dlc_close(): an exported wrapper that takes rfcomm_mutex and re-checks the session, around a __rfcomm_dlc_accept() that the two in-core callers, which already hold the mutex, keep using. Reproduced on a KASAN + PROVE_LOCKING kernel with a BR/EDR peer emulated over /dev/vhci: the peer brings up an ACL link, opens L2CAP on the RFCOMM PSM, starts a session, opens a dlc on a channel bound with BT_DEFER_SETUP, and sends DISC after the socket is accepted. recv() on the accepted socket then hits: Oops: general protection fault KASAN: null-ptr-deref in range [0x0000000000000010-0x0000000000000017] RIP: 0010:rfcomm_dlc_accept+0x54/0x350 Call Trace: rfcomm_sock_recvmsg+0x1cd/0x230 sock_recvmsg+0x166/0x1c0 __sys_recvfrom+0x20d/0x300 0x10 is the offset of sock in struct rfcomm_session. With this patch the same run completes with recv() returning 0 and no report, and lockdep stays quiet, confirming rfcomm_mutex is still taken before lock_sock on this path as it is on the thread side. | ||||

| CVE-2026-80821 | 1 Linux | 1 Linux Kernel | 2026-09-04 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: nvmet: pci-epf: put CQ ref on create_cq mapping failure nvmet_pci_epf_create_cq() calls nvmet_cq_create(), which takes a reference on the controller and installs the completion queue. If the subsequent PCI address-space mapping fails or returns a too-small partial mapping, the function jumps to err_internal / err_unmap_queue without calling nvmet_cq_put(). The matching put in nvmet_pci_epf_delete_cq() is gated on NVMET_PCI_EPF_Q_LIVE, which is only set after the mapping succeeds, so teardown never releases these references. A remote PCI host that drives Create IO CQ commands with a failing PRP1/pci_addr therefore leaks the CQ and a controller reference on each attempt. Drop the CQ reference on the mapping-failure paths. The err_internal and err_unmap_queue labels are only reachable after nvmet_cq_create() has succeeded, so this pairs the create/put correctly. | ||||

| An improper input validation vulnerability in the configuration service for processing encrypted credential data has been identified in Tapo C200 v5. An attacker can send oversized crypted ciphertext values that may trigger exception handling failures, due to insufficient validation, causing the affected device to crash or restart. Successful exploitation may temporarily disrupt HTTPS management and monitoring functionality, resulting in a denial-of-service (DoS) condition until the service recovers. | ||||
| CVE-2026-50553 | 2026-09-04 | N/A | ||
| Note Mark is an open-source note-taking application. Prior to version 0.19.5, Note Mark validates book and note slug values with the OpenAPI/huma tag pattern:"[a-z0-9-]+". huma compiles this with regexp.MustCompile(s.Pattern) and tests it with patternRe.MatchString(str), an UNANCHORED match. Because the pattern is not anchored (^...$), any string that merely CONTAINS one [a-z0-9-] substring passes validation. A slug such as ../../../../../../tmp/escape is accepted and stored verbatim. The data-export CLI commands (note-mark migrate export and note-mark migrate export-v1) join these unsanitized slugs straight into the output path with path.Join / filepath.Join, then os.MkdirAll the directory and os.Create the note file. path.Join resolves the ../ segments, so the note content file is written OUTSIDE the configured export directory. The export process commonly runs as root (default in Docker / bare-metal admin usage), so this is a root-privilege arbitrary directory create + file write. This issue has been patched in version 0.19.5. | ||||
| CVE-2026-80428 | 1 Ilias | 1 Ilias | 2026-09-04 | 9.8 Critical |
| ILIAS before versions 9.22, 10.10, and 11.3 contains an unauthenticated PHP object injection vulnerability that allows unauthenticated attackers to execute arbitrary code by injecting serialized objects through the LTI authentication endpoint and triggering deserialization via the Shibboleth back-channel logout endpoint. Attackers can write arbitrary serialized objects into session storage, then exploit an available POP gadget through the logout endpoint's unrestricted deserialization to write attacker-controlled PHP content to a web-accessible path and achieve remote code execution as the web server user. | ||||
