| ImageMagick before 7.1.2-33 contains a memory leak vulnerability in PerlMagick that fails to free values returned when reading image properties. Attackers can repeatedly trigger property reads through five affected PerlMagick code locations to exhaust memory and cause denial of service. |
| ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak caused by a missing cleanup when the -set profile option is used. An attacker who induces a user to process images with the -set profile option can leak memory, potentially exhausting resources and causing a denial of service. |
| ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak in its XML parsing code, where allocated memory is not released when parsing reaches the nesting depth limit. Attackers can supply crafted, deeply nested XML data to trigger the leak, causing memory exhaustion and denial of service. |
| ImageMagick before 7.1.2-33 contains a memory leak vulnerability in the FPX encoder that allows attackers to exhaust memory by supplying a crafted image. Attackers can submit crafted images for FPX encoding to leak memory repeatedly, causing resource exhaustion and denial of service. |
| ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak in the MSL decoder that fails to release allocated memory when processing a crafted MSL image. Attackers can supply crafted MSL files for processing to repeatedly leak memory, causing resource exhaustion and denial of service. |
| The Bluetooth host pre-allocates a bt_conn object (a "reservation") from the fixed acl_conns[] pool for every connectable advertising set it starts, in le_adv_start_add_conn() in subsys/bluetooth/host/adv.c. When an incoming peripheral connection completes, find_pending_connect() in subsys/bluetooth/host/hci_core.c looked that reservation up using only the identity and the peer address, with a directed-then-undirected fallback, and had no knowledge of which advertising set actually terminated. With CONFIG_BT_EXT_ADV_MAX_ADV_SET > 1, where the LE Enhanced Connection Complete event is cached until the LE Advertising Set Terminated event identifies the set, this lookup can return the reservation belonging to a different, still-running advertising set.
The defect is reachable over the air by any adjacent device. If an application runs two connectable extended advertising sets on the same identity — one undirected and one directed at a peer P (the common "directed reconnect to a bonded central while still accepting new centrals" pattern) — a remote initiator whose address maps to P connecting on the undirected set causes the directed set's reservation to be consumed instead. The initiator address is chosen freely by the remote device and is not authenticated at link establishment, so no bonding, pairing or prior relationship is required to trigger the mis-attribution.
The undirected set's own reservation is then stranded: its BT_ADV_ENABLED flag has already been cleared, and le_adv_stop_free_conn() — the only path that returns a reservation to the pool — is reached only for sets that are still enabled, so bt_le_ext_adv_stop() returns early and the object is never released. Each occurrence permanently consumes one CONFIG_BT_MAX_CONN slot until bt_disable() or reboot. In application patterns that restart the directed advertising set after each disconnect, an attacker can repeat the sequence until the pool is exhausted, after which connectable advertising fails with -ENOMEM and the device can no longer accept connections. As a side effect the directed set keeps advertising without a reservation, so a genuine connection on it is dropped by bt_hci_disconnect(). The impact is availability only; no memory corruption or information disclosure results, and configurations with a single advertising set are unaffected. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: fix kmap_local leak in write_mft_record_nolock() error paths
write_mft_record_nolock() maps the MFT record folio with
kmap_local_folio(), but the pre_write_mst_fixup() and
bio_add_folio() failure paths jump to the error label without
unmapping it. kmap_local mappings are stack-ordered per task, so
leaking one corrupts the nesting for any outer mapping.
Unmap the folio on those error paths too. |
| ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak in the handling of the -cdl (color decision list) option, where allocated memory is not cleaned up after use. Attackers can supply input that causes the -cdl option to be processed, repeatedly leaking memory and degrading availability through resource exhaustion. |
| ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak in the handling of XMP profiles by various decoders. Attackers can supply images with a crafted XMP profile that leak memory each time they are processed, leading to resource exhaustion and denial of service. |
| ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak in the JNG encoder that fails to release allocated memory when processing a crafted image. Attackers can supply crafted images that are encoded to JNG to leak memory, potentially causing resource exhaustion and a limited denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
spi: mtk-snfi: unregister ECC engine on probe failure and remove() callback
mtk_snand_probe() registers the on-host NAND ECC engine, but teardown was
missing from both probe unwind and remove-time cleanup. Add a devm cleanup
action after successful registration so
nand_ecc_unregister_on_host_hw_engine() runs automatically on probe
failures and during device removal. |
| In the Linux kernel, the following vulnerability has been resolved:
PCI: mediatek-gen3: Prevent leaking IRQ domains when IRQ not found
In mtk_pcie_setup_irq(), the IRQ domains are allocated before the
controller's IRQ is fetched. If the latter fails, the function
directly returns an error, without cleaning up the allocated domains.
Hence, reverse the order so that the IRQ domains are allocated after the
controller's IRQ is found.
This was flagged by Sashiko during a review of "[PATCH v6 0/7] PCI:
mediatek-gen3: add power control support". |
| In the Linux kernel, the following vulnerability has been resolved:
net: thunderx: fix PTP device ref leak in nicvf_probe()
cavium_ptp_get() acquires a reference to the PTP PCI device
through pci_get_device(). If any initialization step fails
after cavium_ptp_get(), the PTP PCI device reference is leaked.
Add a common error path to release the PTP reference before
returning from probe failures. |
| In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v5: Immediately exec priority drop following activate
With GICv5 an interrupt of equal or lower priority cannot be signalled
until there has been a priority drop. This is done via the GIC CDEOI
system instruction. Once this has been executed, the hardware is able
to signal the next interrupt if there is one.
As all interrupts are programmed to have the same priority, no new
interrupts can be signalled until the priority drop has happened. This
can cause issues when, for example, an interrupt remains active while
a long running process takes place, such as when injecting a physical
interrupt into a guest VM in software.
The GICv5 driver has so far done the priority drop as part of
irq_eoi(), i.e., at the same time as deactivating the interrupt. This
means that any long running process (or VM) could block incoming
interrupts, effectively causing a denial of service for all other
interrupts.
Rather than doing the EOI as part of irq_eoi() (which the name would
suggest would be a good place for it), move it to happen immediately
after acknowledging an interrupt in the main GICv5 interrupt
handler. The deactivation of interrupts (GIC CDDI) remains implemented
as part of irq_eoi(), which means that the same interrupt cannot be
signalled a second time until deactivated by software. |
| ImageMagick before 7.1.2-33 contains a memory leak vulnerability in the MAT decoder that fails to release allocated memory in a specific error path. Attackers can supply crafted MAT files that trigger this error path repeatedly, causing small memory leaks that gradually consume process memory. |
| In the Linux kernel, the following vulnerability has been resolved:
gve: fix XSK buffer leak on error descriptor
When the error bit is set in the RX completion descriptor, the buf_state
and its attached buffer should be freed. In the case of AF_XDP ZC, the
XSK buffer was not freed, leading to a leak.
This issue was caught by LLM. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: use finish_no_open() for non-regular inodes
An O_CREAT open can find an existing symlink or another non-regular
inode. cifs_atomic_open() calls finish_open() on it and attaches a
cifsFileInfo. Symlink inodes have no CIFS release operation, so the
dentry reference held by cifsFileInfo is leaked. FMODE_OPENED also
prevents the VFS from following the symlink.
Track whether cifs_do_create() returned an open server handle. For
non-regular inodes, close the handle if present, remove the pending
open, and call finish_no_open() so the VFS can continue the lookup.
Do not set FMODE_CREATED unless a regular file was opened. For
O_NOFOLLOW with __O_REGULAR, return -ELOOP before the VFS's
-EFTYPE check.
Defer closing a legacy POSIX handle on a non-regular inode until
after inode lookup. This avoids closing it again if lookup fails. |
| In the Linux kernel, the following vulnerability has been resolved:
of/overlay: don't leak fragment references when changeset init fails
init_overlay_changeset() stores the number of initialized fragments
in ovcs->count only on full success. When find_target() or the
__symbols__ lookup fails partway through, the target and overlay
references taken for the fragments initialized so far are never
dropped: free_overlay_changeset() bounds its cleanup loop by
ovcs->count, which is still 0.
Store the running count on the error path so free_overlay_changeset()
puts whatever was set up. The store is guarded by ovcs->fragments
because on the allocation-failure path cnt still holds the counting
pass total while there is no fragments array; everywhere else cnt
only counts fully-initialized fragments. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: RFCOMM: free the skb when the DLC has no owner
rfcomm_recv_data() hands the skb to d->data_ready() and returns 0
without freeing it, so the callback owns the skb from that point on.
The tty implementation frees it when the DLC has been detached from its
device:
static void rfcomm_dev_data_ready(struct rfcomm_dlc *dlc,
struct sk_buff *skb)
{
struct rfcomm_dev *dev = dlc->owner;
if (!dev) {
kfree_skb(skb);
return;
}
The socket implementation returns without freeing it, and the skb is
leaked.
A connected DLC can have no owner: rfcomm_sock_destruct() clears
d->owner, while the DLC itself stays on the session until it is closed.
Data frames that arrive in that window still find d->state ==
BT_CONNECTED in rfcomm_recv_data() and are handed to the callback, one
leaked skb each.
The leak does not stop on its own either. The remote runs out of
credits only once RFCOMM_RX_THROTTLED is set, and for a socket the only
place that sets it is rfcomm_sk_data_ready() itself, below the return.
rfcomm_process_dlcs() keeps granting credits, so the remote keeps
sending and the leak keeps growing.
Free the skb, as the tty side does. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix objects stuck in free_by_rcu_ttrace
do_call_rcu_ttrace() returns early when call_rcu_ttrace_in_progress is set
and leaves the objects in free_by_rcu_ttrace. __free_rcu() frees
waiting_for_gp_ttrace only and clears the flag. Hence the objects that
free_bulk() or __free_by_rcu() added while RCU tasks trace GP was in flight
stay in free_by_rcu_ttrace until free_bulk() or alloc_bulk() is called for
the same bpf_mem_cache again, which may never happen. The number of such
objects is not bounded.
Turn call_rcu_ttrace_in_progress into three states:
0 - idle
1 - __free_rcu() is queued
2 - __free_rcu() is queued and free_by_rcu_ttrace got more objects since
do_call_rcu_ttrace() sets 2. __free_rcu() does cmpxchg(1 -> 0) and starts
the next GP when it fails. It cannot clear the flag first and check
free_by_rcu_ttrace later, since bpf_mem_alloc_destroy() frees bpf_mem_cache
without waiting for RCU callbacks when the flag is zero.
Now __free_rcu() queues itself, so the one that didn't see 'draining' may
do call_rcu_tasks_trace() after rcu_barrier_tasks_trace() in
free_mem_alloc(). Queue it under rcu_read_lock() and do synchronize_rcu()
before the barriers. Calling rcu_barrier_tasks_trace() twice works too, but
creating and destroying hash maps in a loop on many cpus slows down to one
free_mem_alloc() per GP and kworkers pile up. |
