How to fix?

Upgrade SLES:15.5 kernel-obs-build to version 5.14.21-150500.55.124.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-obs-build package and not the kernel-obs-build package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

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.
