CVE-2025-37794 is a medium severity vulnerability in the Linux kernel's mac80211 Wi-Fi subsystem. It involves improper handling of the vif's transmit queue (txq) in the ieee80211_do_stop() function, which can lead to a NULL pointer dereference and kernel crash. This occurs because packets may still be dequeued after ieee80211_do_stop() due to concurrent scheduling without proper state checks. The flaw was observed to cause crashes in drivers like ath12k where driver-private data is cleared prematurely.
