CVE-2026-74367

Local denial of service via incomplete vdev rollback

Published Aug 15, 2026 · Updated Aug 15, 2026

Improper error handling in the Linux ath12k Wi-Fi driver from 6.13 allows local users to cause system instability during vdev creation. The ath12k_mac_vdev_create() error paths retain arvif state or skip DP peer and vdev rollback after WMI creation or deletion failures. Exploitation requires an affected ath12k device and a driver error during virtual-device creation; the resulting stale state can interrupt service.
