CVE-2023-33288

System crash via uncanceled charger work

Published May 22, 2023 · Updated Mar 18, 2025

Use-after-free in the Linux kernel before 6.2.9 allows local users to crash the system by racing removal of the bq24190 charger driver. bq24190_remove unregisters and frees the power-supply object without synchronously canceling input_current_limit_work, which can later dereference the freed object. Exploitation requires local low-privileged access, the bq24190 charger driver, an external-power event that queues the work, and a concurrent module-removal race; the documented consequence is a system crash.
