{"id":"CVE-2026-46095","summary":"md/md-llbitmap: raise barrier before state machine transition","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmd/md-llbitmap: raise barrier before state machine transition\n\nMove the barrier raise operation before calling llbitmap_state_machine()\nin both llbitmap_start_write() and llbitmap_start_discard(). This\nensures the barrier is in place before any state transitions occur,\npreventing potential race conditions where the state machine could\ncomplete before the barrier is properly raised.","modified":"2026-06-27T11:54:43.346529588Z","published":"2026-05-27T12:58:48.179Z","related":["openSUSE-SU-2026:10954-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46095.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/9142f00a9287ca38152717e3e88a033a27774e7f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9701d51dd378380ba05293fa391e8ba01065ae8d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ef4ca3d4bf09716cff9ba00eb0351deadc8417ab"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46095.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46095"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5ab829f1971dc99f2aac10846c378e67fc875abc"},{"fixed":"9142f00a9287ca38152717e3e88a033a27774e7f"},{"fixed":"9701d51dd378380ba05293fa391e8ba01065ae8d"},{"fixed":"ef4ca3d4bf09716cff9ba00eb0351deadc8417ab"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46095.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.18.0"},{"fixed":"6.18.27"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46095.json"}}],"schema_version":"1.7.5"}
