This also keeps\nmac_work from running over an already suspended HIF, which the previous\nsplit (async cancel under the lock, sync cancel after release) would\nhave allowed.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/3114d479f2a1d31b2e6214c395794c6e5715e579","https://git.kernel.org/stable/c/33d29aeb4c0eede92622a7d04ea492b94c30f089","https://git.kernel.org/stable/c/36c73b86a09f0e51c0f81a75c8945b6c5557ff27","https://git.kernel.org/stable/c/44be85af3e1772ffb3332feafedad2a73b22854c","https://git.kernel.org/stable/c/4506e229b2e468b8c64bcf52c50c41a3bf2e633e"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-80938","score":0.00173,"percentile":0.06641,"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).
