Unity Linux 20.1070e Security Update: kernel (UTSA-2025-986300)

medium Nessus Plugin ID 269133

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-2025-986300 advisory.

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

crypto: qat - Fix ADF_DEV_RESET_SYNC memory leak

Using completion_done to determine whether the caller has gone away only works after a complete call. Furthermore it's still possible that the caller has not yet called wait_for_completion, resulting in another potential UAF.

Fix this by making the caller use cancel_work_sync and then freeing the memory safely.

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.
