A malformed beacon with\nan ESR IE positioned at the end of the buffer could cause an\nout-of-bounds read, potentially triggering a kernel panic.\n\nAdd a boundary check to ensure that the ESR IE body and the subsequent\nbytes are within the limits of the frame before attempting to access\nthem.\n\nThis prevents OOB reads caused by malformed beacon frames.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","score":7.1},"cwes":[],"references":["https://git.kernel.org/stable/c/38292407c2bb5b2b3131aaace4ecc7a829b40b76","https://git.kernel.org/stable/c/502ddcc405b69fa92e0add6c1714d654504f6fd7","https://git.kernel.org/stable/c/bb5940193d813449540d8d3a82abc045be41f48a","https://git.kernel.org/stable/c/bf323db1d883c209880bd92f3b12503e3531c3fc","https://git.kernel.org/stable/c/c03cb111628924827351e19baa5b073e9b0d723d"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:17:07.138532058+00:00"},"epss":{"cve":"CVE-2025-68254","score":0.00276,"percentile":0.19808,"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).
