Echo: linux: security update to 6.1.176-1

medium Tenable Self-Hosted Container Security Plugin ID 458748

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: md/raid5: fix soft lockup in
 retry_aligned_read() When retry_aligned_read() encounters an overlapped stripe, it releases the stripe via
 raid5_release_stripe() which puts it on the lockless released_stripes llist. In the next raid5d loop
 iteration, release_stripe_list() drains the stripe onto handle_list (since STRIPE_HANDLE is set by the
 original IO), but retry_aligned_read() runs before handle_active_stripes() and removes the stripe from
 handle_list via find_get_stripe() -> list_del_init(). This prevents handle_stripe() from ever processing
 the stripe to resolve the overlap, causing an infinite loop and soft lockup. Fix this by using
 __release_stripe() with temp_inactive_list instead of raid5_release_stripe() in the failure path, so the
 stripe does not go through the released_stripes llist. This allows raid5d to break out of its loop, and
 the overlap will be resolved when the stripe is eventually processed by handle_stripe(). (CVE-2026-46051)

Solution

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