Echo: linux: security update to 6.1.170-1

high Tenable Cloud Security Plugin ID 460463

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: wifi: cfg80211: cancel pmsr_free_wk in
 cfg80211_pmsr_wdev_down When the nl80211 socket that originated a PMSR request is closed,
 cfg80211_release_pmsr() sets the request's nl_portid to zero and schedules pmsr_free_wk to process the
 abort asynchronously. If the interface is concurrently torn down before that work runs,
 cfg80211_pmsr_wdev_down() calls cfg80211_pmsr_process_abort() directly. However, the already- scheduled
 pmsr_free_wk work item remains pending and may run after the interface has been removed from the driver.
 This could cause the driver's abort_pmsr callback to operate on a torn-down interface, leading to
 undefined behavior and potential crashes. Cancel pmsr_free_wk synchronously in cfg80211_pmsr_wdev_down()
 before calling cfg80211_pmsr_process_abort(). This ensures any pending or in-progress work is drained
 before interface teardown proceeds, preventing the work from invoking the driver abort callback after the
 interface is gone. (CVE-2026-31548)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
