CVE-2024-49857

Kernel crash via unset NDP cipher pointer

Published Oct 21, 2024 · Updated Aug 5, 2026

NULL pointer dereference in Linux 6.11 iwlwifi secured NDP ranging allows local users to crash or corrupt the kernel. In iwl_mvm_ftm_put_target_v2(), target.cipher is left unset before the selected key cipher is written through that pointer while building a firmware range request. Triggering requires CAP_NET_ADMIN for the wireless device, an associated Intel Wi-Fi access point with a PASN entry, and a crafted peer-measurement request; the result is a kernel oops or kernel-state corruption.
