Tested it with another driver (ax88179_178a), since\nI don't have a aqc111 device to test it, but the code looks very similar.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":6.8},"cwes":["CWE-125","CWE-787"],"references":["https://git.kernel.org/stable/c/36311fe98f55dea9200c69e2dd6d6ddb8fc94080","https://git.kernel.org/stable/c/404998a137bcb8a926f7c949030afbe285472593","https://git.kernel.org/stable/c/afb8e246527536848b9b4025b40e613edf776a9d","https://git.kernel.org/stable/c/b416898442f2b6aa9f1b2f2968ce07e3abaa05f7","https://git.kernel.org/stable/c/d90df6da50c56ad8b1a132e3cf86b6cdf8f507b7"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49051","score":0.00437,"percentile":0.38007,"date":"2026-10-31"},"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).
