Echo: linux: security update to 6.1.153-1

high Tenable Self-Hosted Container Security Plugin ID 461882

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: mm/damon/sysfs: fix use-after-free in
 state_show() state_show() reads kdamond->damon_ctx without holding damon_sysfs_lock. This allows a use-
 after-free race: CPU 0 CPU 1 ----- ----- state_show() damon_sysfs_turn_damon_on() ctx =
 kdamond->damon_ctx; mutex_lock(&damon_sysfs_lock); damon_destroy_ctx(kdamond->damon_ctx);
 kdamond->damon_ctx = NULL; mutex_unlock(&damon_sysfs_lock); damon_is_running(ctx); /* ctx is freed */
 mutex_lock(&ctx->kdamond_lock); /* UAF */ (The race can also occur with damon_sysfs_kdamonds_rm_dirs() and
 damon_sysfs_kdamond_release(), which free or replace the context under damon_sysfs_lock.) Fix by taking
 damon_sysfs_lock before dereferencing the context, mirroring the locking used in pid_show(). The bug has
 existed since state_show() first accessed kdamond->damon_ctx. (CVE-2025-39877)

Solution

Update the linux library and its related packages to version 6.1.153-1 or later.
