medium Nessus Plugin ID 280553
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-2025-992424 advisory.In the Linux kernel, the following vulnerability has been resolved:
drm/msm/mdp5: Fix global state lock backoff
We need to grab the lock after the early return for !hwpipe case.
Otherwise, we could have hit contention yet still returned 0.
Fixes an issue that the new CONFIG_DRM_DEBUG_MODESET_LOCK stuff flagged in CI:
