Other\nmode-changes callers in sysfs and driver code are missing fbcon-related\nsteps.\n\nWith the new helper, ps3fb and sh_mobile_lcdcfb no longer maintain\nfbcon state themselves.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/07f7e46833f71472e30da54a50dacdf48521bdd3","https://git.kernel.org/stable/c/3130e7bf43ecfe3a15bcf90b9698e0764a2d8d08","https://git.kernel.org/stable/c/6f611e5e5f3327cf2e2daabe6ee5acac58cc784e","https://git.kernel.org/stable/c/d33589eff3d40439b3c83e8da0d07d20df797d50","https://git.kernel.org/stable/c/ed7e9715849abd0816b8487b0d12ebd05d6e938b"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-80786","score":0.00209,"percentile":0.10943,"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).
