Echo: linux: security update to 6.1.176-1

medium Tenable Cloud Security Plugin ID 455237

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: ipc/shm: serialize orphan cleanup with
 shm_nattch updates shm_destroy_orphaned() walks the shm idr under shm_ids(ns).rwsem, but that does not
 serialize all fields tested by shm_may_destroy(). In particular, shm_nattch is updated while holding
 shm_perm.lock, and attach paths can do that without holding the rwsem. Do not decide that an orphaned
 segment is unused before taking the object lock. Move the shm_may_destroy() check under shm_perm.lock,
 matching the other destroy paths, and unlock the segment when it no longer qualifies for removal.
 (CVE-2026-52930)

Solution

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