Since\n\"urb->context\" contains \"parent\", it is always defined, while \"dev\" is not\ndefined if the URB it too short.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/18cbce43363c9f84b90a92d57df341155eee0697","https://git.kernel.org/stable/c/3433680b759646efcacc64fe36aa2e51ae34b8f0","https://git.kernel.org/stable/c/616eee3e895b8ca0028163fcb1dce5e3e9dea322","https://git.kernel.org/stable/c/6fe9f3279f7d2518439a7962c5870c6e9ecbadcf","https://git.kernel.org/stable/c/f31693dc3a584c0ad3937e857b59dbc1a7ed2b87"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2025-68343","score":0.00186,"percentile":0.08098,"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).
