Unity Linux 20.1060a Security Update: kernel (UTSA-2025-992908)

medium Nessus Plugin ID 281421

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-2025-992908 advisory.

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

 PM: EM: fix memory leak with using debugfs_lookup()

 When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once.

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.
