CVE-2026-68471

Kernel memory corruption via unvalidated Wi-Fi MLE length

Published Aug 15, 2026 · Updated Aug 15, 2026

Out-of-bounds access in the Linux kernel allows adjacent attackers to corrupt kernel memory via crafted Wi-Fi MLE management frames. ieee80211_mle_common_size trusts the advertised common-info length, while ieee80211_mle_size_ok omits validation for Reconfiguration and Priority Access MLEs. No association or local privileges are required; passive receipt during scanning can disclose or corrupt kernel memory or panic the host.
