Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-011113)

medium Nessus Plugin ID 308779

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-2026-011113 advisory.

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

media: s5p-mfc: Clear workbit to handle error condition

During error on CLOSE_INSTANCE command, ctx_work_bits was not getting cleared. During consequent mfc execution NULL pointer dereferencing of this context led to kernel panic. This patch fixes this issue by making sure to clear ctx_work_bits always.

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.
