Echo: linux: security update to 6.1.158-1

high Tenable Cloud Security Plugin ID 461684

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: media: tuner: xc5000: Fix use-after-
 free in xc5000_release The original code uses cancel_delayed_work() in xc5000_release(), which does not
 guarantee that the delayed work item timer_sleep has fully completed if it was already running. This leads
 to use-after-free scenarios where xc5000_release() may free the xc5000_priv while timer_sleep is still
 active and attempts to dereference the xc5000_priv. A typical race condition is illustrated below: CPU 0
 (release thread) | CPU 1 (delayed work callback) xc5000_release() | xc5000_do_timer_sleep()
 cancel_delayed_work() | hybrid_tuner_release_state(priv) | kfree(priv) | | priv = container_of() // UAF
 Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensure that the timer_sleep is properly
 canceled before the xc5000_priv memory is deallocated. A deadlock concern was considered: xc5000_release()
 is called in a process context and is not holding any locks that the timer_sleep work item might also
 need. Therefore, the use of the _sync() variant is safe here. This bug was initially identified through
 static analysis. [hverkuil: fix typo in Subject: tunner -> tuner] (CVE-2025-39994)
