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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","score":8.1},"cwes":["CWE-125"],"references":["https://git.kernel.org/stable/c/0406d746574e875d8778552eb674fcfbf5330bfb","https://git.kernel.org/stable/c/04f612dc03427e0b1ac80a2611b5ac0ba93ac446","https://git.kernel.org/stable/c/0970dd47726a57e52013594e9fbf667586eb3673","https://git.kernel.org/stable/c/1a52a05471494546f955a58e8c170c0c796c52d5","https://git.kernel.org/stable/c/7e7741c8315e4160aead00a60cdd6f81ab880717"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-64444","score":0.0028,"percentile":0.20347,"date":"2026-10-26"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
