CVE-2025-38606

Kernel crash via detached radio pointer dereference

Published Aug 19, 2025 · Updated May 11, 2026

NULL pointer dereference in Linux ath12k 6.14 through 6.15.9 and 6.16.0 allows local users to crash the kernel during beacon loss. ath12k_mac_handle_beacon_miss_iter() dereferences arvif->deflink->ar after a completed or aborted P2P scan deletes the scan vdev and detaches the interface from its radio. Reachability requires a P2P-capable ath12k device, the default dummy P2P interface, prior scan teardown, and a station beacon-miss event; the documented consequence is a kernel crash.
