Unity Linux 20.1050e Security Update: kernel (UTSA-2026-005099)

high Nessus Plugin ID 296865

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-2026-005099 advisory.

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

 media: venus: fix use after free in vdec_close

 There appears to be a possible use after free with vdec_close().
 The firmware will add buffer release work to the work queue through HFI callbacks as a normal part of decoding. Randomly closing the decoder device from userspace during normal decoding can incur a read after free for inst.

 Fix it by cancelling the work in vdec_close.

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.
