Unity Linux 20.1070a Security Update: kernel (UTSA-2025-986441)

medium Nessus Plugin ID 267955

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-2025-986441 advisory.

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

 media: venus: hfi: avoid null dereference in deinit

 If venus_probe fails at pm_runtime_put_sync the error handling first calls hfi_destroy and afterwards hfi_core_deinit. As hfi_destroy sets core->ops to NULL, hfi_core_deinit cannot call the core_deinit function anymore.

 Avoid this null pointer derefence by skipping the call when necessary.

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.
