This fix does not allow these AIDs to work, but will\nprevent the firmware crash.\n\nThis crash was only seen on IFTYPE_AP interfaces, and the fix does not\nappear to have an effect on IFTYPE_STATION behavior.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/1a4b802afe15c5b33b2dcb37a594aba2fa215d52","https://git.kernel.org/stable/c/35835ff71e6e618155578b8e3905597edd5f601c","https://git.kernel.org/stable/c/4d0bf21e3e20619d51d06c0c36207aabab8b712c","https://git.kernel.org/stable/c/6dbe70f9ef14d8ac1c24bf19fd9510978a3ab952","https://git.kernel.org/stable/c/9d63dd026644fa612a1fd348d5d3ab5d73df7fb8"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-53317","score":0.00162,"percentile":0.05312,"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).
