Kernel compromise via ath12k list corruption
Published Jul 10, 2025 · Updated Aug 5, 2026
Memory corruption in the ath12k Wi-Fi driver in Linux allows physically proximate attackers to compromise the kernel over Wi-Fi. During concurrent WLAN recovery and virtual-interface removal, ath12k_core_halt() resets only the arvifs list head, leaving member nodes linked through stale pointers that later list_del() operations read and overwrite. An unauthenticated attacker must be within radio range of an active ath12k interface; repeated malformed management and deauthentication frames can reach the race and crash the system.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
