"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath12k: Correct tid cleanup when tid setup fails\n\nCurrently, if any error occurs during ath12k_dp_rx_peer_tid_setup(),\nthe tid value is already incremented, even though the corresponding\nTID is not actually allocated. Proceed to\nath12k_dp_rx_peer_tid_delete() starting from unallocated tid,\nwhich might leads to freeing unallocated TID and cause potential\ncrash or out-of-bounds access.\n\nHence, fix by correctly decrementing tid before cleanup to match only\nthe successfully allocated TIDs.\n\nAlso, remove tid-- from failure case of ath12k_dp_rx_peer_frag_setup(),\nas decrementing the tid before cleanup in loop will take care of this.\n\nCompile tested only."

"value": "AV:A - The vulnerable path is entered from the ath12k WiFi driver's mac80211 `sta_state` callback when a peer is added in response to received 802.11 management frames, so the attacker must be within radio range of the AP/STA, i.e. on the same wireless segment.\nAC:L - The attacker controls both sides of the trigger — repeatedly transmitting auth/assoc frames from spoofed MACs (each allocating 17 GFP_ATOMIC REO queue descriptors) and immediately deauthing to race peer teardown against the 17-TID setup loop — so the `ath12k_dp_rx_peer_frag_setup()` failure needed to reach `rx_tid[17]` is attacker-driven rather than beyond their influence.\nPR:N - In AP mode mac80211/hostapd add the station (NOTEXIST→NONE) upon an 802.11 Authentication frame, before any credentials, PSK, or 802.1X exchange is verified, so the attacker needs no account or key on the target.\nUI:N - Exploitation requires only that the attacker transmit 802.11 frames to a listening ath12k AP; no action by a local user or administrator is needed.\nS:U - The out-of-bounds read/write and invalid free corrupt kernel heap memory managed by the same kernel security authority; there is no crossing into a hypervisor, guest, or sandbox boundary.\nC:H - `ath12k_dp_reo_cmd_send()` performs a 128-byte `memcpy` from `&peer->rx_tid[17]`, copying out-of-bounds heap contents (including kernel pointers and DMA addresses) into a cached REO command element, and the OOB-read address is also handed to hardware — an unbounded adjacent-memory read.\nI:H - The bug yields out-of-bounds writes past `peer->rx_tid[]` (`vaddr = NULL`, `active = false`, plus an 8-byte write one entry past the REO LUT), a `kfree()` of a pointer synthesized from out-of-bounds bytes (arbitrary-free primitive), and a REO hardware queue-descriptor write at an attacker-influenced physical address — all usable for control-flow-relevant heap corruption.\nA:H - Freeing a wild pointer and `dma_unmap_single()` on a bogus DMA address reliably produce slab corruption, IOMMU faults, or an oops/panic, taking down the kernel and the WiFi interface."
