CVE-2023-52530

Adjacent code execution via stale GTK pointer

Published Mar 2, 2024 · Updated Aug 5, 2026

Use-after-free in Linux kernel mac80211 4.14 through 6.6-rc4 allows adjacent attackers to execute code through WoWLAN GTK rekeying. The ieee80211_gtk_rekey_add() path returns a pointer to a freed key when ieee80211_key_link() treats an identical reinstall as success. Reachability requires attacker-controlled Wi-Fi rekey material during suspend and resume; dereferencing the stale key can disclose or corrupt kernel memory or panic the host.
