Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992319)
medium Nessus Plugin ID 280484
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-2025-992319 advisory.In the Linux kernel, the following vulnerability has been resolved:
regulator: core: fix use_count leakage when handling boot-on
I found a use_count leakage towards supply regulator of rdev with boot-on option.
regulator_dev A regulator_dev B (boot-on) (boot-on) use_count=0 supply use_count=1
In case of rdev(A) configured with `regulator-boot-on', the use_count of supplying regulator(B) will increment inside regulator_enable(rdev->supply).
Thus, B will acts like always-on, and further balanced regulator_enable/disable cannot actually disable it anymore.
However, B was also configured with `regulator-boot-on', we wish it could be disabled afterwards.
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
