A flaw was found in the Linux kernel's MediaTek mt7925 Wi-Fi driver. When the device is reset, suspended, or unregistered, a pending work item (mlo_pm_work) can continue to execute. This can lead to the work item accessing memory that has already been freed (a use-after-free vulnerability) or sending commands to unavailable firmware. The most significant consequence is a denial of service, which can cause system instability or crashes.
