A flaw was found in the Linux kernel's lp8727 power supply driver. A race condition can occur during the release of an interrupt request (IRQ), where a delayed work item might be re-armed after the associated memory has been freed. This can lead to a use-after-free vulnerability, potentially causing memory corruption and system instability.
