CVSS v3.1 |
| SurrealDB before 1.1.1 contains a format string vulnerability in the rquickjs Exception::throw_type function when scripting is enabled. Attackers with scripting privileges can supply format string sequences in error inputs to read arbitrary memory or execute code with SurrealDB process privileges. |
| Use of externally-controlled format string in Windows Image Acquisition allows an authorized attacker to elevate privileges locally. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: target: iscsi: Fix race in discovery auth updates
Separate configfs opens can concurrently update the discovery AuthMethod
parameter. Both callers may free the same value in
iscsi_update_param_value(), causing a double-free.
Protect the lookup and replacement with the discovery TPG access lock,
as used by the other TPG configfs parameter updates. |
| Use of externally-controlled format string in Windows NTFS allows an authorized attacker to elevate privileges locally. |
| Pillow is a Python imaging library. Prior to 13.0.0, Pillow can double free image memory when ImagingScaleAffine encounters a selective allocation failure. The affected fast path handles Transform.EXTENT or pure scale-and-translate Transform.AFFINE operations with the default NEAREST resampling. The output image allocation must succeed while the additional per-column lookup allocation fails, after which the error path deletes image storage that later cleanup releases again. An attacker who can drive such a large Image.transform() operation under memory pressure may trigger the failure. This can crash the process and may corrupt memory. This issue is fixed in version 13.0.0. |
| FreeRDP before 3.32.0 contains a double-free vulnerability in nsc_context_initialize_encode() that leaves dangling plane pointers after a partial buffer growth failure. Attackers using a crafted RDP client can negotiate NSCodec with a large desktop geometry to trigger allocation failure, crashing the server during context teardown. |
| A double free in XKB SetGeometryin X.Org X Server before 21.1.25 and X Wayland before 24.1.14 could be used by attached clients to cause a crash or potentially code in the x server context. |
| A weakness has been identified in libimobiledevice up to 1.4.0. This issue affects the function service_receive of the file src/afc.c of the component AFC Service. Executing a manipulation can lead to double free. The attack may be performed from remote. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way. |
| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Prevent stale XSK buffer release on refill retry
When an XDP redirect to an AF_XDP socket fails because its RX ring is
full, the XSK core frees the buffer. During the subsequent batched refill
of a legacy cyclic RQ, mlx5e also releases the WQE's XSK buffer before
allocating a replacement. If that refill succeeds only partially, a WQE
left without a replacement retains its old buffer pointer.
The buffer can meanwhile be allocated to another WQE. A later refill
retry can then free the live buffer through the stale pointer and publish
the same UMEM frame twice.
Mark the WQE as released immediately after the driver-side free. The flag
is already cleared when a replacement buffer is assigned, so refill
retries no longer release stale pointers.
The failure is silent and produces no kernel warning or splat. A
standalone legacy cyclic-RQ zero-copy libxsk reproducer, using 64-byte UDP
traffic offered at 12 Mpps, detected it: stock stopped after 2,854,914
packets in 4.094 seconds, with 4,542 xdp_rx_ring_full events and 64
ownership/double-publication errors. With this change it processed
356,904,225 packets in 30 seconds despite 571,405 xdp_rx_ring_full events,
with no ownership or data errors. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau: fix double-free in nvif_vmm_dtor
On failure, nouveau_cli_init() calls nouveau_cli_fini() to tear
the client down. Then, nouveau_drm_open() also enters into its
cleanup path and calls nouveau_cli_fini() AGAIN. nouveau_cli_fini()
calls nouveau_vmm_fini():
void
nouveau_vmm_fini(struct nouveau_vmm *vmm)
{
nouveau_svmm_fini(&vmm->svmm);
nvif_vmm_dtor(&vmm->vmm);
vmm->cli = NULL;
}
Inside nvif_vmm_dtor(), vmm->page is freed unconditionally:
void
nvif_vmm_dtor(struct nvif_vmm *vmm)
{
kfree(vmm->page);
nvif_object_dtor(&vmm->object);
}
vmm->page is never cleared after being freed, so the second call of
nvif_vmm_dtor() will cause a double-free.
Found by fuzzing the nouveau driver with a modified Syzkaller:

| In the Linux kernel, the following vulnerability has been resolved:
mtd: core: avoid double-free of OTP NVMEM device
If factory OTP setup fails after the user OTP NVMEM device has been
registered, mtd_otp_nvmem_add() unregisters the user device but leaves
mtd->otp_user_nvmem set. On an error, the caller unregisters it again.
For -EOPNOTSUPP, registration continues and normal teardown unregisters
it again.
Clear mtd->otp_user_nvmem after unregistering it. |
| In the Linux kernel, the following vulnerability has been resolved:
of/overlay: put property on deadprops only after changeset add succeeds
add_changeset_property() links a new property of a not-yet-live
target node into the node's deadprops list before handing it to
of_changeset_add_property(). If that fails, the error path frees the
property but leaves the freed pointer linked in deadprops, and
of_node_release() frees it a second time when the aborted overlay's
node is released.
Record the changeset entry first and link the property into deadprops
only on success. of_changeset_add_property() never looks at the
node's property lists, so the order of the two steps is otherwise
immaterial, and the error path frees a property that nothing
references. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: preserve hidden-group beacon IE ownership
A hidden-group probe-response entry borrows its beacon IEs from the
group's beacon entry. cfg80211_update_assoc_bss_entry() can pass such
an entry to cfg80211_update_known_bss() when merging scan entries
after a channel switch.
Copying the borrowed beacon_ies into the associated entry gives the
same allocation two owners. Releasing the group's beacon entry can
then leave the associated entry pointing to freed IEs, which are
freed again when that entry is released.
Skip beacon IE replacement when the source entry belongs to a hidden
group. Preserve probe-response processing, the subsequent metadata
updates, and the existing rejection path for conflicting hidden
beacon updates. |
| Use of externally-controlled format string in SQL Server allows an authorized attacker to deny service over a network. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: always return -EIOCBQUEUED after btrfs_uring_read_extent_endio
If all bios finish before btrfs_encoded_read_regular_fill_pages()
returns, it calls btrfs_uring_read_extent_endio() and previously
returned the I/O status. A negative errno then made
btrfs_uring_read_extent() unlock and free while
btrfs_uring_read_finished() did the same again.
Return -EIOCBQUEUED so only the deferred path cleans up. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/bridge: samsung-dsim: fix TE GPIO lifetime for host attach
When the Exynos DSI driver was generalized into samsung-dsim, the TE
GPIO acquisition was switched from gpiod_get_optional() to
devm_gpiod_get_optional() while keeping the matching gpiod_put() calls.
That combination is wrong for a managed descriptor.
However, dropping the puts and keeping the managed get is also wrong:
samsung_dsim_register_te_irq() runs from the DSI host attach callback,
and host detach/reattach can happen without destroying the device that
owns the managed action. A second attach would then request the GPIO
again without having released it.
Switch back to a non-managed gpiod_get_optional() and keep the explicit
gpiod_put() on the request_irq() error path and in
samsung_dsim_unregister_te_irq().
