In the Linux kernel, the following vulnerability has been resolved:

media: uvcvideo: Mark invalid entities with id UVC_INVALID_ENTITY_ID

Per UVC 1.1+ specification 3.7.2, units and terminals must have a non-zero unique ID.

``` Each Unit and Terminal within the video function is assigned a unique identification number, the Unit ID (UID) or Terminal ID (TID), contained in the bUnitID or bTerminalID field of the descriptor. The value 0x00 is reserved for undefined ID, ```

If we add a new entity with id 0 or a duplicated ID, it will be marked as UVC_INVALID_ENTITY_ID.

In a previous attempt commit 3dd075fe8ebb ("media: uvcvideo: Require entities to have a non-zero unique ID"), we ignored all the invalid units, this broke a lot of non-compatible cameras. Hopefully we are more lucky this time.

This also prevents some syzkaller reproducers from triggering warnings due to a chain of entities referring to themselves. In one particular case, an Output Unit is connected to an Input Unit, both with the same ID of 1. But when looking up for the source ID of the Output Unit, that same entity is found instead of the input entity, which leads to such warnings.

In another case, a backward chain was considered finished as the source ID was 0. Later on, that entity was found, but its pads were not valid.

Here is a sample stack trace for one of those cases.

OESA-2025-2776 — kernel security update

Affected: openEuler:24.03-LTS-SP2: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

jfs: add check read-only before txBeginAnon() call

Added a read-only check before calling `txBeginAnon` in `extAlloc` and `extRecord`. This prevents modification attempts on a read-only mounted filesystem, avoiding potential errors or crashes.

Call trace: txBeginAnon+0xac/0x154 extAlloc+0xe8/0xdec fs/jfs/jfs_extent.c:78 jfs_get_block+0x340/0xb98 fs/jfs/inode.c:248 __block_write_begin_int+0x580/0x166c fs/buffer.c:2128 __block_write_begin fs/buffer.c:2177 [inline] block_write_begin+0x98/0x11c fs/buffer.c:2236 jfs_write_begin+0x44/0x88 fs/jfs/inode.c:299(CVE-2024-58095)

In the Linux kernel, the following vulnerability has been resolved:

mm: zswap: properly synchronize freeing resources during CPU hotunplug

In zswap_compress() and zswap_decompress(), the per-CPU acomp_ctx of the current CPU at the beginning of the operation is retrieved and used throughout. However, since neither preemption nor migration are disabled, it is possible that the operation continues on a different CPU.

If the original CPU is hotunplugged while the acomp_ctx is still in use, we run into a UAF bug as some of the resources attached to the acomp_ctx are freed during hotunplug in zswap_cpu_comp_dead() (i.e. acomp_ctx.buffer, acomp_ctx.req, or acomp_ctx.acomp).

The problem was introduced in commit 1ec3b5fe6eec ("mm/zswap: move to use crypto_acom…
