CVE-2022-50250
5.5 · MEDIUMOverview
CVE-2022-50250 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 15, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
