A flaw was found in the Linux kernel's power supply charger-manager component. A race condition exists where the system frees charger regulators before their corresponding sysfs entries are unregistered. A local attacker can exploit this by performing a concurrent write to a charger's externally_control sysfs attribute, leading to a use-after-free vulnerability. This can result in system instability, crashes, or potentially arbitrary code execution.
kernel: power: supply: charger-manager: register regulators before exposing sysfs — rated Moderate by Red Hat. Released 2026-09-11, updated 2026-09-16.
