It's OK for the devices the\ndriver itself creates at the module probe time, but if the device is\nbound manually via sysfs interface, this could be -1 as \"none\", and\nthis leads to OOB access for index[] and other parameters.\n\nAdd a sanity check for the card index and warn/correct it if it's a\nvalue out of the range.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/26a25fb4ef4ba2a33069d489feb75a4c36899cca","https://git.kernel.org/stable/c/3a997371ac2957f11a033a4cec2930042dadb7e3","https://git.kernel.org/stable/c/4a3d6c22ca6b6c16e8055fb518aa87f5e043f754","https://git.kernel.org/stable/c/76b6bc38d0f310c0ae1b2a2ebabe2947d92c601a","https://git.kernel.org/stable/c/8adda66edf795d4648f8e26f312e4414c535d25a"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-80969","score":0.00216,"percentile":0.11966,"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).
