| exceljs through 4.4.0 contains a path traversal vulnerability in the Workbook.addImage() function that fails to validate file paths. Attackers can supply arbitrary file paths to read any file accessible to the Node.js process and embed it in the generated workbook. | ||||
| CVE-2026-78206 | 1 Exceljs Project | 1 Exceljs | 2026-08-29 | 7.5 High |
| exceljs through 4.4.0 decompresses all entries from supplied xlsx archives into memory without limits on entry size, total size, or compression ratio. Attackers can upload highly compressed workbooks that expand to gigabytes in memory, exhausting available resources and causing denial of service. | ||||
| CVE-2026-62388 | 1 Nltk | 1 Nltk | 2026-08-29 | 7.5 High |
| NLTK versions before 3.10.0 default to ENFORCE=False in pathsec.py, causing all security validation functions to emit warnings instead of raising exceptions. Attackers can bypass path traversal and pickle deserialization protections by exploiting the disabled security controls that are only active when manually enabled. | ||||
| CVE-2026-80692 | 1 Linux | 1 Linux Kernel | 2026-08-29 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_sync: hold conn in hci_connect_acl/le_sync() callbacks There is theoretical UAF if the conn is freed while the hci_sync task is running. Hold refcount to avoid that. | ||||
| CVE-2026-80702 | 1 Linux | 1 Linux Kernel | 2026-08-29 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: fix guest_memory_dirty bitfield clobbered as size Two sites in vmwgfx_resource.c assign boolean literals to res->guest_memory_size, which is an unsigned long allocation-size field; the intended target is the adjacent res->guest_memory_dirty bitfield. After the assignments the field holds 0 or 1 instead of the resource's MOB allocation size: - vmw_resource_release() writes 0 (false), and - vmw_resource_unbind_list() writes 1 (true). Subsequent revalidation paths read guest_memory_size when computing the dirty page range (vmw_bo_dirty_transfer_to_res()) and the buffer allocation size (vmw_resource_buf_alloc()), producing zero-length walks or wrap-around ranges that read or write past the MOB bitmap. The dirty-tracking intent of the original code (mark the resource as dirtied since the last sync) is also lost, since guest_memory_dirty is never updated. Rename both assignments to guest_memory_dirty. | ||||
| CVE-2026-80707 | 1 Linux | 1 Linux Kernel | 2026-08-29 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: can: j1939: transport: j1939_session_fresh_new(): initialize receive buffer Zero the allocated buffer in j1939_session_fresh_new() to ensure it contains no residual data. While there is a potential performance impact if users allocate maximum sized ETP buffers, most real-world use cases are not noticeably affected since the maximum known buffer size is typically around 65K.

| CVE-2026-80593 | 1 Linux | 1 Linux Kernel | 2026-08-29 | 8.4 High |
| In the Linux kernel, the following vulnerability has been resolved: hwmon: (asus_atk0110) Check package count before accessing element atk_ec_present() walks the management group package returned by the GGRP ACPI method and, for each sub-package, reads its first element: id = &obj->package.elements[0]; if (id->type != ACPI_TYPE_INTEGER) without checking that the sub-package is non-empty. ACPICA allocates the element array with exactly package.count entries, so for a sub-package with a zero count this reads past the allocation. The sibling function atk_debugfs_ggrp_open() performs the same access but skips empty packages with a package.count check first. Add the same check to atk_ec_present() so a malformed firmware package cannot trigger an out-of-bounds read. | ||||
| CVE-2026-80599 | 1 Linux | 1 Linux Kernel | 2026-08-29 | 8.1 High |
| In the Linux kernel, the following vulnerability has been resolved: batman-adv: dat: ensure accessible eth_hdr proto field When batadv_get_vid() accesses the proto field of the ethernet header, it is not checking if the data itself is accessible. The caller is responsible for it. But in contrast to other call sites, batadv_dat_get_vid() and its caller didn't make sure this is true. This could have caused an out-of-bounds access. | ||||
| CVE-2026-80608 | 1 Linux | 1 Linux Kernel | 2026-08-29 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix iommu domain lifetime race during device removal When force_iova mode is enabled, amdxdna_remove() frees xdna->domain. If amdxdna_gem_obj_free() is called after device removal, it may attempt to access xdna->domain, resulting in a use-after-free. Fix the race by adding freeing xdna->domain as a managed release action, so its lifetime is managed by DRM and remains valid until all managed resources are released. | ||||
| CVE-2026-80613 | 1 Linux | 1 Linux Kernel | 2026-08-29 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: veth: fix NAPI leak in XDP enable error path During XDP enablement in veth, if xdp_rxq_info_reg() or xdp_rxq_info_reg_mem_model() fails, the driver rolls back the changes. However, the rollback loop: for (i--; i >= start; i--) { decrements the loop index 'i' before the first iteration. This correctly skips unregistering the rxq for the failed index 'i' (as registration failed or was already cleaned up), but it also erroneously skips calling netif_napi_deli() for rq[i].xdp_napi. Since netif_napi_add() was already called for index 'i', this leaves a dangling napi_struct in the device's napi_list. When the veth device is later destroyed, the freed queue memory (which contains the leaked NAPI structure) can be reused. The subsequent device teardown iterates the NAPI list and corrupts the reallocated memory, leading to UAF. Fix this by explicitly deleting the NAPI association for the failed index 'i' before rolling back the successfully configured queues. | ||||
| CVE-2026-80614 | 1 Linux | 1 Linux Kernel | 2026-08-29 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: net: emac: Fix NULL pointer dereference in emac_probe Move devm_request_irq() after devm_platform_ioremap_resource() so that dev->emacp is mapped before the interrupt handler can fire. An early interrupt hitting emac_irq() would dereference the NULL dev->emacp and crash. Also remove redundant error message. devm_platform_ioremap_resource() already returns an error message with dev_err_probe(). | ||||
| CVE-2026-80706 | 1 Linux | 1 Linux Kernel | 2026-08-29 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: can: softing: fw_parse(): validate firmware record spans fw_parse() reads a fixed record header, a firmware-provided payload, and a trailing checksum without knowing the end of the firmware blob. A truncated record can therefore make those reads exceed the blob. The same record also supplies addresses and lengths for writes into DPRAM. The generic loader uses wrap-prone mixed signed arithmetic for its bounds check, while the application loader does not bound the staging copy at all. Pass the firmware end to the parser and validate the full source record. Use a signed wide offset for generic DPRAM records and validate the application staging span against the mapped DPRAM before copying. | ||||
| CVE-2026-80712 | 1 Linux | 1 Linux Kernel | 2026-08-29 | 8.4 High |
| In the Linux kernel, the following vulnerability has been resolved: spi: spi-qpic-snand: write the feature value before executing SET_FEATURE qcom_spi_send_cmdaddr() programs NAND_FLASH_CMD/NAND_EXEC_CMD and submits the descriptors, which makes the controller execute the command immediately. For SPINAND_SET_FEATURE the value to be written is only placed into NAND_FLASH_FEATURES afterwards, by qcom_spi_io_op(), in a second submission - so the chip is programmed with whatever that register happened to hold from a previous operation, and the intended value is only applied by the *next* SET_FEATURE. Measured on a TP-Link Archer AX55 v1 (IPQ5018, ESMT F50L1G41LB): writing 0x40 to the configuration register (0xb0) leaves the chip at 0x00, and the subsequent write of 0x00 leaves it at 0x40 - every write lands one operation late. This stayed unnoticed until v6.18 added SPI-NAND OTP support together with OTP entries for ESMT chips. spinand_otp_rw() enables OTP mode, reads, and disables it again, and mtd_otp_nvmem_add() does this during MTD registration. With the off-by-one, the "disable" write actually applies the previously requested value, so CFG_OTP_ENABLE ends up set: the chip stays in OTP mode, every subsequent array read returns the OTP area instead of the array (UBI reports an empty device) and all writes fail with -EIO because the OTP area is write protected. On this board that makes the whole flash unusable and the device unbootable. Write the feature value into NAND_FLASH_FEATURES as part of the same transaction, before NAND_EXEC_CMD. While at it, copy only the bytes the operation actually carries - the previous code dereferenced a 4-byte pointer on a one-byte buffer (spinand->scratchbuf). With this patch the flash contents read back bit-identical to a known-good dump of the same board taken under the vendor firmware (md5-verified across partitions), and writes work. | ||||
| CVE-2026-80622 | 1 Linux | 1 Linux Kernel | 2026-08-29 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: char: tlclk: fix use-after-free in tlclk_cleanup() This patch improves the module cleanup process in the tlclk driver to prevent potential use-after-free and race conditions. Currently, the file_operations structure does not specify the .owner field, which could allow the module to be unloaded while user-space processes are still interacting with the device. Additionally, the tlclk_cleanup() function frees the alarm_events memory before ensuring that blocked processes in the waitqueue are fully awakened and that the switchover_timer has completed. To address these cases, this patch: - Sets '.owner = THIS_MODULE' in tlclk_fops to safely defer module unloading while the device is in use. - Updates tlclk_cleanup() to explicitly wake up all blocked readers (wake_up_all), properly release hardware I/O regions, and safely delete the timer (timer_delete_sync) prior to freeing memory. | ||||

| In the Linux kernel, the following vulnerability has been resolved: ipv6: guard against possible NULL deref in __in6_dev_stats_get() dev_get_by_index_rcu() could return NULL if the original physical device is unregistered. Found by Sashiko. | ||||
| CVE-2026-80656 | 1 Linux | 1 Linux Kernel | 2026-08-29 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: hfsplus: Add a sanity check for btree node size Syzbot reported an uninit-value bug in [1] with a corrupted HFS+ image, during the file system mounting process, specifically while loading the catalog, a corrupted node_size value of 1 caused the rec_off argument passed to hfs_bnode_read_u16() (within hfs_bnode_find()) to be excessively large. Consequently, the function failed to return a valid value to initialize the off variable, triggering the bug [1]. Every node starts from BTree node descriptor: struct hfs_bnode_desc. So, the size of node cannot be lesser than that. However, technical specification declares that: "The node size (which is expressed in bytes) must be power of two, from 512 through 32,768, inclusive." Add a check for btree node size base on technical specification.

| CVE-2026-80663 | 1 Linux | 1 Linux Kernel | 2026-08-29 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: tools/power/x86/intel-speed-select: Harden daemon pidfile open Avoid symlink-based pidfile clobbering by opening the pidfile with O_NOFOLLOW and validating it with fstat() before locking/writing. The daemon currently uses a fixed pidfile path under /tmp. A local unprivileged user can pre-create a symlink at that path and cause a root-run daemon instance to write into an attacker-chosen file. | ||||
| CVE-2026-80665 | 1 Linux | 1 Linux Kernel | 2026-08-29 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: nv: Inject SEA if kvm_translate_vncr() can't resolve PFN kvm_handle_vncr_abort() assumes that s1_walk_result conveys an abort when kvm_translate_vncr() returns -EFAULT. This is not always the case as it's possible to encounter 'late' failures on the output of S1 translation, e.g. a GFN outside of the memslots. Fix it by preparing an external abort before returning from kvm_translate_vncr(). Get rid of the BUG_ON() in the fault injection path while at it. | ||||
| CVE-2026-80683 | 1 Linux | 1 Linux Kernel | 2026-08-29 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: SCO: give the socket its own sco_conn reference sco_conn_del() drops a reference it does not own. It takes one transient reference via sco_conn_hold_unless_zero() and releases it with the sco_conn_put() that follows sco_sock_hold(); the additional put in the !sk branch releases a second one: conn = sco_conn_hold_unless_zero(conn); ... sk = sco_sock_hold(conn); sco_conn_unlock(conn); sco_conn_put(conn); if (!sk) { sco_conn_put(conn); return; } When close() races the controller's Disconnection Complete, sco_chan_del() clears conn->sk and drops the socket's reference while sco_conn_del() is running. sco_conn_del() then sees sk == NULL, its own put drops the count to zero and frees the conn, and the second put writes to the freed kref: BUG: KASAN: slab-use-after-free in sco_conn_put.part.0+0x1a/0x190 Write of size 4 at addr ffff8881099dec74 by task kworker/u17:3/413 Workqueue: hci1 hci_rx_work Call Trace: sco_conn_put.part.0+0x1a/0x190 hci_disconn_complete_evt+0x1ee/0x3e0 hci_event_packet+0x54a/0x650 hci_rx_work+0x321/0x3d0 Allocated by task 413: sco_conn_add+0x72/0x1a0 sco_connect_cfm+0x88/0x670 Freed by task 413: sco_conn_del.isra.0+0x3f/0xf0 hci_disconn_complete_evt+0x1ee/0x3e0 refcount_t: underflow; use-after-free. The root cause is that the socket stores the connection without holding a reference of its own. __sco_chan_add() does: sco_pi(sk)->conn = conn; so the socket borrows whatever reference its caller happened to hold, and the callers paper over that with ad-hoc holds and puts. Give the socket a counted reference instead: __sco_chan_add() takes one and it is released together with the channel (sco_chan_del()) and in sco_sock_destruct(). With the socket holding its own reference, sco_conn_del() no longer needs the extra put and the redundant hold in sco_conn_ready() goes away. Making the socket own its reference means the connection is now actually freed on the error paths of sco_connect() where it used to leak, which in turn runs sco_conn_free() and its hci_conn_drop(conn->hcon). To keep the hci_conn accounting balanced, make that ownership explicit as well: sco_conn_add() consumes one hci_conn reference and the sco_conn owns it for its lifetime. sco_connect() hands over the reference returned by hci_connect_sco() and no longer drops it on the error paths; sco_connect_cfm(), which is not given a reference, takes one with hci_conn_hold() before handing it to sco_conn_add() (and drops it again if the allocation fails); and the explicit hci_conn_hold() in sco_conn_ready() is removed. Every reference then has a single, clear owner. | ||||
