medium Nessus Plugin ID 274037
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-2025-989479 advisory.In the Linux kernel, the following vulnerability has been resolved:
drm/msm/mdp5: Return error code in mdp5_mixer_release when deadlock is detected
There is a possibility for mdp5_get_global_state to return
-EDEADLK when acquiring the modeset lock, but currently global_state in mdp5_mixer_release doesn't check for if an error is returned.
To avoid a NULL dereference error, let's have mdp5_mixer_release check if an error is returned and propagate that error.
Patchwork: https://patchwork.freedesktop.org/patch/485181/
Tenable has extracted the preceding description block directly from the Unity Linux security advisory.
