Description
A flaw was found in the Linux kernel's power supply subsystem. A race condition can occur if a power supply device is unregistered while an event callback is still executing, causing the driver data to be deallocated while still in use. This leads to a use-after-free condition where the kernel attempts to access released memory. Consequently, this flaw can cause kernel memory corruption or a system crash, resulting in a denial of service (DoS).
