      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath6kl: clamp assoc request/response lengths before subtracting IE offsets\n\nath6kl_cfg80211_connect_event() subtracts fixed IE offsets from\nassoc_req_len (-= 4) and assoc_resp_len (-= 6), both u8, with no lower\nbound. The aggregate check recently added to ath6kl_wmi_connect_event_rx()\nbounds the declared lengths from above (their sum must fit the received\nevent), but an assoc request/response shorter than its fixed offset still\nunderflows here: the u8 wraps to ~250, and cfg80211_connect_result() /\ncfg80211_roamed() then treat that wrapped value as the IE length and copy\nthat many bytes out of the small assoc_info buffer to user space via\nnl80211, disclosing adjacent slab memory.\n\nClamp both lengths to their offsets before subtracting.\n\nFound by 0sec (https://0sec.ai) using automated source analysis; the\nmissing lower bound is evident from source. Compile-tested.",
