CVE-2022-50735

Kernel crash via premature mt76 status work

Published Dec 24, 2025 · Updated Dec 24, 2025

NULL pointer dereference in the Linux kernel mt76 USB Wi-Fi driver allows attackers to crash the kernel during device startup. The mt76u_status_worker runs while the device is not yet running, and its transmit-status path dereferences an uninitialized pointer. Reachability requires an affected kernel with the mt76 USB driver and a device-startup state that schedules status work before initialization completes.
