Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992487)

medium Nessus Plugin ID 280294

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-992487 advisory.

 In the Linux kernel, the following vulnerability has been resolved:

 dm stats: check for and propagate alloc_percpu failure

 Check alloc_precpu()'s return value and return an error from dm_stats_init() if it fails. Update alloc_dev() to fail if dm_stats_init() does.

 Otherwise, a NULL pointer dereference will occur in dm_stats_cleanup() even if dm-stats isn't being actively used.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
