Echo: linux: security update to 6.1.176-1

high Tenable Cloud Security Plugin ID 458968

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: media: em28xx: fix use-after-free in
 em28xx_v4l2_open() em28xx_v4l2_open() reads dev->v4l2 without holding dev->lock, creating a race with
 em28xx_v4l2_init()'s error path and em28xx_v4l2_fini(), both of which free the em28xx_v4l2 struct and set
 dev->v4l2 to NULL under dev->lock. This race leads to two issues: - use-after-free in v4l2_fh_init() when
 accessing vdev->ctrl_handler, since the video_device is embedded in the freed em28xx_v4l2 struct. - NULL
 pointer dereference in em28xx_resolution_set() when accessing v4l2->norm, since dev->v4l2 has been set to
 NULL. Fix this by moving the mutex_lock() before the dev->v4l2 read and adding a NULL check for dev->v4l2
 under the lock. (CVE-2026-31583)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
