It also requires completely tearing down a netdev during a fairly\ntight race window.)","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-416"],"references":["https://git.kernel.org/stable/c/4907596f25b1720fa948371ac5f6c1f8da10a5bc","https://git.kernel.org/stable/c/5506aec795135cdd4cbf4e845929155663b25055","https://git.kernel.org/stable/c/59e932ded949fa6f0340bf7c6d7818f962fa4fd2","https://git.kernel.org/stable/c/915a92182e2cda9cd7d2479020a44c6eda986f7c","https://git.kernel.org/stable/c/a75bbcb10cb21acc169b785e9804f57d97873a9c"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2026-64178","score":0.00304,"percentile":0.22959,"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).
