{"id":"CVE-2025-68374","summary":"md: fix rcu protection in md_wakeup_thread","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmd: fix rcu protection in md_wakeup_thread\n\nWe attempted to use RCU to protect the pointer 'thread', but directly\npassed the value when calling md_wakeup_thread(). This means that the\nRCU pointer has been acquired before rcu_read_lock(), which renders\nrcu_read_lock() ineffective and could lead to a use-after-free.","modified":"2026-04-02T13:03:37.419882Z","published":"2025-12-24T10:33:04.046Z","related":["SUSE-SU-2026:0962-1","SUSE-SU-2026:1081-1","SUSE-SU-2026:20555-1","SUSE-SU-2026:20599-1","SUSE-SU-2026:20615-1","SUSE-SU-2026:20667-1","SUSE-SU-2026:20720-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1","openSUSE-SU-2026:10039-1","openSUSE-SU-2026:10301-1","openSUSE-SU-2026:20287-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68374.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0dc76205549b4c25705e54345f211b9f66e018a0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/21989cb5034c835b212385a2afadf279d8069da0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a4bd1caf591faeae44cb10b6517e7dacb5139bda"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f98b191f78124405294481dea85f8a22a3eb0a59"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68374.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68374"},{"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":"4469315439827290923fce4f3f672599cabeb366"},{"fixed":"21989cb5034c835b212385a2afadf279d8069da0"},{"fixed":"a4bd1caf591faeae44cb10b6517e7dacb5139bda"},{"fixed":"f98b191f78124405294481dea85f8a22a3eb0a59"},{"fixed":"0dc76205549b4c25705e54345f211b9f66e018a0"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68374.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.5.0"},{"fixed":"6.12.63"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.17.13"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.18.0"},{"fixed":"6.18.2"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68374.json"}}],"schema_version":"1.7.5"}
