that originated from WiFi rekeying while suspended; a malicious or compromised AP on the same wireless segment can trigger that rekey path on resume.\nAC:L - This is a deterministic use-after-free once an identical GTK is passed into ieee80211_gtk_rekey_add() and the returned key_conf is used; an adjacent attacker who controls rekeying can drive that condition without relying on an uncontrolled race.\nPR:N - No privileges on the victim host are required; an unauthenticated adjacent WiFi peer/AP can induce GTK rekey during WoWLAN without local credentials or capabilities.\nUI:N - Exploitation does not need a deliberate user action beyond normal association and suspend/WoWLAN operation, which occurs automatically on typical laptops and phones.\nS:U - Impact remains within the local kernel/host trust boundary; this is a standard in-kernel UAF privilege-escalation class bug, not a VM/IOMMU/sandbox escape.\nC:H - Use-after-free of the ieee80211_key object lets an attacker reclaim and read attacker-controlled substitute memory, enabling arbitrary kernel information disclosure.\nI:H - The resume path immediately writes RX sequence/PN state through the freed key_conf via ieee80211_set_key_rx_seq(), giving a heap UAF write primitive suitable for control-flow hijacking.\nA:H - Dereferencing or mutating the freed key reliably causes kernel oops/panic even when not fully exploited, so availability impact is high." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
