Ideally we would also want to signal that the IRQ\nthread no longer needs to be run after the timeout is hit to avoid the\nextra check for a valid transfer.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/01bbf25c767219b14c3235bfa85906b8d2cb8fbc","https://git.kernel.org/stable/c/551060efb156c50fe33799038ba8145418cfdeef","https://git.kernel.org/stable/c/83309dd551cfd60a5a1a98d9cab19f435b44d46d","https://git.kernel.org/stable/c/88db8bb7ed1bb474618acdf05ebd4f0758d244e2","https://git.kernel.org/stable/c/b4e002d8a7cee3b1d70efad0e222567f92a73000"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:18:08.089039631+00:00"},"epss":{"cve":"CVE-2025-68746","score":0.00144,"percentile":0.03657,"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).
