{"id":"CVE-2026-45888","summary":"md/raid1: fix memory leak in raid1_run()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmd/raid1: fix memory leak in raid1_run()\n\nraid1_run() calls setup_conf() which registers a thread via\nmd_register_thread(). If raid1_set_limits() fails, the previously\nregistered thread is not unregistered, resulting in a memory leak\nof the md_thread structure and the thread resource itself.\n\nAdd md_unregister_thread() to the error path to properly cleanup\nthe thread, which aligns with the error handling logic of other paths\nin this function.\n\nCompile tested only. Issue found using a prototype static analysis tool\nand code review.","modified":"2026-07-15T01:49:06.581063716Z","published":"2026-05-27T12:16:59.751Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45888.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/6abc7d5dcf0ee0f85e16e41c87fbd06231f28753"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b37588b0282a2b3cdda9db1d53712745ce66dea0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c94fd6e8a71efd047ff36930e840f3c25679e136"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ec10e3dc93994b87adf7c759a4639fe34013989a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45888.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45888"},{"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":"97894f7d3c2966164516a8a5109674763d3a55e1"},{"fixed":"c94fd6e8a71efd047ff36930e840f3c25679e136"},{"fixed":"ec10e3dc93994b87adf7c759a4639fe34013989a"},{"fixed":"b37588b0282a2b3cdda9db1d53712745ce66dea0"},{"fixed":"6abc7d5dcf0ee0f85e16e41c87fbd06231f28753"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45888.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.9.0"},{"fixed":"6.12.75"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.14"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45888.json"}}],"schema_version":"1.7.5"}
