When a malicious AP sends an\nAssocResponse whose last IE has only one byte remaining in the frame\n(the element_id byte lands at pkt_len-1), the loop reads pIE->length\nfrom pframe[pkt_len], which is one byte past the allocated receive buffer.\n\nAdditionally, even when the header bytes are in bounds, pIE->length\nitself can extend the data window beyond pkt_len, silently passing a\ntruncated IE to the handler functions.\n\nAdd two guards at the top of the loop body:\n  1. Break if fewer than sizeof(*pIE) bytes remain (can't read header).\n  2. Break if the IE's declared data extends past pkt_len.\n\n## Affected\n\n- `Linux >= 554c0a3abf216c991c5ebddcdb2c08689ecd290b < 889ca6000ac7fa73457b041848fcb08e0d51b809`\n- `Linux >= 554c0a3abf216c991c5ebddcdb2c08689ecd290b < 1a52a05471494546f955a58e8c170c0c796c52d5`\n- `Linux >= 554c0a3abf216c991c5ebddcdb2c08689ecd290b < 0406d746574e875d8778552eb674fcfbf5330bfb`\n- `Linux >= 554c0a3abf216c991c5ebddcdb2c08689ecd290b < 0970dd47726a57e52013594e9fbf667586eb3673`\n- `Linux >= 554c0a3abf216c991c5ebddcdb2c08689ecd290b < 04f612dc03427e0b1ac80a2611b5ac0ba93ac446`\n- `Linux >= 554c0a3abf216c991c5ebddcdb2c08689ecd290b < 7e7741c8315e4160aead00a60cdd6f81ab880717`\n- `Linux >= 554c0a3abf216c991c5ebddcdb2c08689ecd290b < f9654207e92283e0acac5d64fe5f8835383b5a23`\n- `Linux 4.12`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":45,"depthScoreParts":{"impact":44.6,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
