The out-of-range win_sz is then used in TID_WINDOW_SZ() to\ncompute a kzalloc size and stored in rxtid->hold_q_sz, leading to\nzero-size or overflowed allocations and subsequent out-of-bounds access.\n\nClean up any previously active aggregation session for the TID first,\nthen return early when win_sz is out of the valid range, instead of\nproceeding with a broken allocation size."

"value": "AV:A - Exploitation requires a malicious WiFi peer (rogue AP or associated client) to trigger ADDBA handling; firmware passes WMI_ADDBA_REQ_EVENTID over the radio link to the ath6kl driver, placing the attacker on the same wireless segment rather than a remote IP network path.\nAC:L - An adjacent attacker can reliably send crafted 802.11 ADDBA requests with out-of-range buffer/window sizes to firmware, which forwards the invalid win_sz to the host; no special memory layout, race, or rare timing is required beyond normal WiFi association.\nPR:N - No local Linux privileges are needed; any associated WiFi peer can induce the malformed ADDBA event. The bug is not reachable via user namespaces or unprivileged local syscalls without controlling the WiFi link/firmware messages.\nUI:N - Once the victim device is associated to WiFi (common on phones, embedded, and IoT), the attacker can send ADDBA and follow-up data frames without any additional victim action beyond routine wireless connectivity.\nS:U - Heap corruption and kernel privilege escalation occur within the same kernel security domain; this is not a VM escape, IOMMU bypass, or cross-authority sandbox breakout.\nC:H - Out-of-bounds access to hold_q allows reading/writing adjacent kernel heap memory (e.g., skb pointers and metadata); OOB kernel heap access is treated as arbitrary memory disclosure potential per kernel CVSS guidance.\nI:H - OOB writes to hold_q entries (struct sk_buff pointers, is_amsdu, seq_no) corrupt kernel heap state and can be leveraged for control-flow hijacking and local privilege escalation, not merely a bounded modification.\nA:H - Invalid win_sz can yield zero-size allocations and hold_q_sz=0 (divide-by-zero in AGGR_WIN_IDX) or inconsistent buffers, causing kernel oops/panic or persistent disruption when aggregation receives subsequent frames."
