With only a raw pointer and no structural\nreference, the mm_struct can be freed before the scheduler runs the job.\n\nFix this by calling mmgrab() to hold a structural mm_count reference for\nthe lifetime of the job, paired with mmdrop() in every cleanup path.","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/6875ee2bef48f5d9f045d81a8a4d68893f768a8a","https://git.kernel.org/stable/c/e8fadbffc19a233d1eedebfb8df0f522d1388280","https://git.kernel.org/stable/c/faebb7ba1ac65fa5810b640df02ce04e509fdc11"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68380","score":0.00133,"percentile":0.02793,"date":"2026-10-31"},"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).
