| Name | CVE-2022-50250 | 
| 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. |
