"value": "AV:A - The BSS parameters that trigger the bug originate from attacker-transmitted beacon/probe-response frames, which cfg80211 accepts into the scan cache without rejecting a BSSID equal to a local interface address; an attacker in WiFi range can therefore induce the victim's SME to auth/assoc to a self-addressed BSS. Per WiFi frame-injection guidance this is Adjacent.\nAC:L - The attacker fully controls the beacon's BSSID/MLD address and SSID, and the victim STA's MAC address is passively observable from its probe requests; the victim's connection attempt is routine auto-join behavior that the attacker can force by deauthing it from its real AP.\nPR:N - A rogue AP needs no credentials or prior association with the victim, and the failure occurs in the pre-authentication auth/assoc path before any key exchange.\nUI:N - Automatic reconnection to a known/matching SSID by wpa_supplicant or the kernel SME requires no human action, and the attacker can trigger it on demand with a deauth.\nS:U - The WARN_ON and the corrupted MLME state are entirely within the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - No out-of-bounds read, uninitialized memory disclosure, or other read primitive is created; the attacker gains no access to kernel or user data.\nI:L - The attacker's rogue BSS causes mac80211 to tear down the legitimate association and leaves inconsistent state behind (`vif.cfg.ap_addr` set to the interface's own address, and in the MLO case a link_sta bearing our own address inserted into `local->link_sta_hash`), a bounded modification of kernel connection state rather than arbitrary write.\nA:H - The path reaches `WARN_ON()` in `sta_info_insert_check()`, which is a kernel panic on the many deployments running `panic_on_warn=1`, and can be triggered repeatedly to persistently deny WiFi connectivity."
