CVE-2024-35937

Kernel-memory disclosure via truncated A-MSDU headers

Published May 19, 2024 · Updated Aug 5, 2026

Out-of-bounds read in Linux kernel 6.3 through 6.8.5 allows physically proximate attackers to disclose kernel memory via Wi-Fi frames. ieee80211_is_valid_amsdu in net/wireless/util.c copied an A-MSDU subframe header before confirming that the remaining socket buffer contained the complete header. Exposure requires reception of a malformed A-MSDU over an adjacent wireless link; the read can disclose kernel memory or interrupt the system.
