A flaw was found in the Linux kernel's bq25980 power supply driver. A race condition during interrupt handling can lead to a use-after-free vulnerability, where the system attempts to access memory that has already been released. This can be triggered when an interrupt fires after the power supply handle is freed but before the interrupt handler is unregistered. Successful exploitation of this flaw can cause a system crash, resulting in a Denial of Service (DoS), or lead to silent memory corruption.
