CVE-2024-43848

Kernel crash via miscomputed TTLM worker pointer

Published Aug 17, 2024 · Updated Aug 5, 2026

Type confusion in Linux mac80211 6.10 through 6.10.2 allows physically proximate attackers to crash the kernel via Wi-Fi. ieee80211_teardown_ttlm_work passes teardown_ttlm_work to container_of but subtracts the offset of neg_ttlm_timeout_work.work, producing an sdata pointer 32 bytes before the object. A rogue 802.11be MLD access point in radio range can negotiate TTLM and acknowledge teardown to queue the worker, causing kernel memory corruption and a deterministic crash without credentials or user interaction.
