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.","published":"2026-08-10T12:03:58.536Z","modified":"2026-08-14T04:04:08.395601167Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.18.42"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/6875ee2bef48f5d9f045d81a8a4d68893f768a8a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e8fadbffc19a233d1eedebfb8df0f522d1388280"},{"type":"WEB","url":"https://git.kernel.org/stable/c/faebb7ba1ac65fa5810b640df02ce04e509fdc11"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68380.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68380"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-14T04:04:08.395601167Z"}}
