CVE-2025-38293

Kernel panic via corrupted ath11k interface list

Published Jul 10, 2025 · Updated Aug 5, 2026

Denial of service in the Linux kernel ath11k driver allows local users to trigger a kernel panic during concurrent WLAN recovery and vif removal. ath11k_core_halt() reinitializes only the arvifs list head, leaving the following interface node linked to a head that no longer links back; list_del() then detects the corruption. Exploitation requires an ath11k device and a WLAN recovery to race with interface removal, and the bounded consequence is a host crash.
