Echo: linux: security update to 6.1.176-1

critical Tenable Cloud Security Plugin ID 458220

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: batman-adv: fix fragment reassembly
 length accounting batman-adv keeps a running payload length for queued fragments and uses it to validate a
 fragment chain before reassembly. That accounting currently allows the accumulated fragment length to be
 truncated during updates. As a result, malformed fragment chains can bypass the intended validation and
 drive reassembly with inconsistent length state, leading to a local denial of service. Fix the accounting
 by storing the accumulated length in a length-typed field and rejecting update overflows before the
 existing validation logic runs. The fix was verified against the original reproducer and against valid
 fragment reassembly paths. (CVE-2026-52914)

Solution

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