Unity Linux 20.1070e Security Update: kernel (UTSA-2026-013378)
medium Nessus Plugin ID 307948
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-2026-013378 advisory.In the Linux kernel, the following vulnerability has been resolved:
drm/mipi-dsi: Detach devices when removing the host
Whenever the MIPI-DSI host is unregistered, the code of mipi_dsi_host_unregister() loops over every device currently found on that bus and will unregister it.
However, it doesn't detach it from the bus first, which leads to all kind of resource leaks if the host wants to perform some clean up whenever a device is detached.
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.See Also
