Echo: linux: security update to 6.1.176-1

medium Tenable Cloud Security Plugin ID 455401

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: gfs2: prevent NULL pointer dereference
 during unmount When flushing out outstanding glock work during an unmount, gfs2_log_flush() can be called
 when sdp->sd_jdesc has already been deallocated and sdp->sd_jdesc is NULL. Commit 35264909e9d1 ("gfs2: Fix
 NULL pointer dereference in gfs2_log_flush") added a check for that to gfs2_log_flush() itself, but it
 missed the sdp->sd_jdesc dereference in gfs2_log_release(). Fix that. (CVE-2026-53048)

Solution

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