A concurrent read of the monmap debugfs\nfile can enter monmap_show() after ceph_monc_stop() has freed\nmonc->monmap, triggering a use-after-free.\n\nRemove the debugfs files before stopping the OSD and monitor clients.\ndebugfs_remove() drains active handlers and prevents new accesses, so\nthe debugfs callbacks can no longer race the rest of client teardown.","published":"2026-08-10T11:59:19.302Z","modified":"2026-08-14T04:03:21.362704875Z","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":"6.6.148"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/8f5a3abc54ba24dbceb14cc3a719908c4f688091"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b9fedda2f628e030384228de0dafc574b7fb0c2f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d3dc8889d39a676bf840132bd5c5c48cb0daba23"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e4c804726c4afce3ba648b982d564f6af2cfa328"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fc1010e7e0204ece6cc0f9af4f473e9553535eab"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68153.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68153"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-14T04:03:21.362704875Z"}}
