**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A potential deadlock situation can occur during chip recovery in the Linux kernel, specifically in the wifi: mt76: mt7921s module. This happens when the kernel worker reset work holds a lock and waits for the kernel thread stat worker to be parked, while stat worker waits for the release of the same lock. This causes a deadlock, resulting in hung tasks messages and possible rebooting of the device. The issue is resolved by preventing the execution of stat worker during chip recovery. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
