If the stored IE data ends with only an\n   element_id byte and no length byte, pIE->length is read one byte\n   past the end of the buffer.\n\n - join_cmd_hdl() walks pnetwork->ies during station join and has\n   the same problem under the same conditions.\n\nBoth buffers are filled from AP beacon and probe-response frames, so a\nmalicious AP that sends a truncated final IE can trigger the issue.\n\nApply the two-guard pattern established in update_beacon_info():\n  1. Break if fewer than sizeof(*pIE) bytes remain.\n  2. Break if the IE's declared data extends past the buffer end.","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/402f13ec95945f34a210b28df1f8740d3d4a58c5","https://git.kernel.org/stable/c/4c21eec80cf502d9ea18e0b946246b2376452786","https://git.kernel.org/stable/c/605ebd94d0f469204f3c9f2f84acc71e43e2780f","https://git.kernel.org/stable/c/a830bdc82461353bf7b1f8a2ad2689bf5d2de444","https://git.kernel.org/stable/c/ad2637c46ef8b8ae0894372a2d39fdfcdc420a1e"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-64442","score":0.00287,"percentile":0.21041,"date":"2026-10-25"},"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).
