After the upcoming conversion to static attributes, it will also\ntrigger resource file updates via sysfs_update_groups().\n\nAdd a CAP_SYS_ADMIN check to prevent unprivileged users from performing BAR\nresize operations.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/25ec7f57deceec633f27bc93b615f951e2ade814","https://git.kernel.org/stable/c/b722a607f858b9cd036075ea0efad553fb98e982","https://git.kernel.org/stable/c/cbf0628c0b7db86c5ce36451f088101546acbf1d","https://git.kernel.org/stable/c/d02dd7ce8e52b66b7d3b6eca2a7d81e7f5b10a62"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-97505","score":0.00157,"percentile":0.04787,"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).
