This action frees the arvif pointer.\nSubsequently, there is a check involving arvif, which will result in a\nread-after-free scenario.\n\nFix this by moving this check after arvif is again assigned via call to\nath12k_mac_assign_link_vif().\n\nTested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1"

"value": "AV:A - The vulnerable code is a mac80211 chanctx-assignment op driven by 802.11 events — cross-radio scanning, band steering/BSS-transition requests, channel-switch announcements and MLO link reconfiguration — so an attacker within WiFi range (rogue/evil-twin AP or frame injection) can drive the radio migration that frees the arvif.\nAC:L - The attacker can repeatedly force band/radio migrations of the link vif via beacons, CSA and MLO link reconfiguration, and the freeing plus the stale read happen deterministically on that path with no race to win; heap grooming to control the reallocated object is standard.\nPR:N - An adjacent 802.11 attacker needs no credentials on the target — background scans and auto-connect to a spoofed known SSID reach the path pre-authentication, and no local account or capability is required.\nUI:N - Background scanning across radios and auto-reconnect to saved networks occur without any user action, and CSA/band-steering frames are processed automatically by the connected station.\nS:U - The freed object, the corrupted structures and the resulting code execution all reside in the kernel's own security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:H - Taking the `goto flush` branch runs `ath12k_mac_vif_cache_flush()` on the freed arvif, using freed bytes as `arvif->link_id` to index `ahvif->cache[]` and returning `arvif->ar` from freed memory for the caller to dereference — an out-of-bounds/arbitrary read primitive over kernel memory.\nI:H - The same use-after-free path performs writes through freed-memory-derived pointers (`ath12k_mac_bss_info_changed()`, `ath12k_mac_conf_tx()`, key-cache flush, and the caller's `arvif->punct_bitmap` store), giving a heap-spray-controlled write primitive suitable for control-flow hijack.\nA:H - Dereferencing freed and reallocated memory as pointers reliably produces a kernel oops/panic even when not exploited further, taking down the affected system."
