Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992286)

medium Nessus Plugin ID 280448

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-2025-992286 advisory.

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

btrfs: fix ulist leaks in error paths of qgroup self tests

In the test_no_shared_qgroup() and test_multiple_refs() qgroup self tests, if we fail to add the tree ref, remove the extent item or remove the extent ref, we are returning from the test function without freeing the old_roots ulist that was allocated by the previous calls to btrfs_find_all_roots(). Fix that by calling ulist_free() before returning.

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.
