The station may not\nhave a link STA for every valid link of the vif, so mt792x_sta_to_link()\ncan return NULL for a link that belongs to the vif but not to the station.\n\nThe function currently dereferences mlink before checking whether the\nlink WCID is ready. If mlink is NULL, setting or clearing\nMT_WCID_FLAG_HDR_TRANS dereferences a NULL pointer.\n\nSkip links without a station link before touching mlink->wcid.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1e608cae1ba0b4a600b752efa223fd2be376b143","https://git.kernel.org/stable/c/96ea44f2269f30364cffa054ee3a87e595bef0d4","https://git.kernel.org/stable/c/d86883f7e8f03a5b81b4e59f2c0b6c05f79e01fd","https://git.kernel.org/stable/c/f1ee53e08fdd2906e90c6a6d71e1368fcd52bfc3"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68311","score":0.00168,"percentile":0.0608,"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).
