Echo: linux: security update to 6.1.176-1

critical Tenable Cloud Security Plugin ID 455388

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: add some missing log locking
 Function gfs2_logd() calls the log flushing functions gfs2_ail1_start(), gfs2_ail1_wait(), and
 gfs2_ail1_empty() without holding sdp->sd_log_flush_lock, but these functions require exclusion against
 concurrent transactions. To fix that, add a non-locking __gfs2_log_flush() function. Then, in gfs2_logd(),
 take sdp->sd_log_flush_lock before calling the above mentioned log flushing functions and
 __gfs2_log_flush(). (CVE-2026-53049)

Solution

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