Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 459339

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: fs/adfs: validate nzones in
 adfs_validate_bblk() Reject ADFS disc records with a zero zone count during boot block validation, before
 the disc record is used. When nzones is 0, adfs_read_map() passes it to kmalloc_array(0, ...) which
 returns ZERO_SIZE_PTR, and adfs_map_layout() then writes to dm[-1], causing an out-of-bounds write before
 the allocated buffer. adfs_validate_dr0() already rejects nzones != 1 for old-format images. Add the
 equivalent check to adfs_validate_bblk() for new-format images so that a crafted image with nzones == 0 is
 rejected at probe time. Found by syzkaller. (CVE-2026-52992)

Solution

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