CVE-2022-49528

Availability disruption via enabled-regulator probe cleanup

Published Feb 26, 2025 · Updated Aug 15, 2026

A regulator cleanup flaw in Linux kernel 4.13 through 5.18.2 allows local users to disrupt availability after a dw9714 probe error. The dw9714_probe error path leaves the VCC regulator enabled before managed teardown releases it, triggering a warning in _regulator_put. Reachability requires a system with a DW9714 focus actuator and a failed probe; the record does not identify the availability loss as a hang or crash.
