{"id":"DEBIAN-CVE-2022-50250","details":"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-\u003esupply).  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.","modified":"2026-09-01T20:04:58.035212124Z","published":"2025-09-15T14:15:35.623Z","upstream":["CVE-2022-50250"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-50250"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2022-50250.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2022-50250.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2022-50250.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
