Per kernel guidance, WiFi frame injection is Adjacent.\nAC:L - The attacker controls every precondition: SSID hiding, BSSID, the two channels, the beacon/probe-response pairs that build the hidden groups, and the CSA that fires `cfg80211_update_assoc_bss_entry()`; the victim\u0027s routine background scans supply the rest without attacker effort. The freed object\u0027s size is attacker-chosen via IE length, so heap grooming is also under attacker control.\nPR:N - No credentials or account on the target system are needed; beacons, probe responses and public action frames are unauthenticated and unprotected (beacon protection/BIGTK is rarely deployed), so a rogue AP or frame injector reaches the code with zero privileges.\nUI:N - Scanning, beacon processing and CSA handling are performed automatically by the kernel for an associated STA \u2014 no user action is required, and the attacker can spoof the legitimate AP\u0027s frames against an already-connected victim.\nS:U - The freed `cfg80211_bss_ies` allocation and all corrupted state live in the kernel\u0027s own slab and cfg80211 BSS list; no VM, IOMMU or sandbox boundary is crossed.\nC:H - The stale `beacon_ies`/`ies` pointers are read by `cmp_bss()` and, critically, copied wholesale to userspace via `NL80211_BSS_BEACON_IES` in scan dumps, disclosing reallocated freed heap contents \u2014 and an attacker-controlled `len` after reallocation extends this to a large out-of-bounds kernel memory read.\nI:H - The shared IEs are freed while still owned by the beacon BSS, so the later `bss_free()` performs a second `kfree_rcu()` on the same object \u2014 a double free of an attacker-sized allocation, a well-established primitive for arbitrary write and control-flow hijack; freed-memory contents also drive rb-tree ordering decisions.\nA:H - Use-after-free reads in `cmp_bss()` plus the subsequent double free corrupt the slab allocator and reliably produce oopses/panics, and the condition can be re-triggered at will by an in-range attacker."
