{"id":"CVE-2026-90390","summary":"md/bitmap: resume array on backlog_store() error path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmd/bitmap: resume array on backlog_store() error path\n\nbacklog_store() suspends the array before checking whether a write-mostly\ndevice exists. If no such device exists, the error path only unlocks\nreconfig_mutex and leaves the array suspended, blocking subsequent I/O.\n\nUse mddev_unlock_and_resume() to release both states.","modified":"2026-09-19T03:47:29.026469378Z","published":"2026-09-17T16:09:24.405Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90390.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/03aad318f0a1f039dddf98739e705fdca3bf0d86"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2911cd0a0f4366a7e06832bc5f0a7fdcc138e4dc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6763fb409a0b4106676a52cf934440d9484b32c8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cc543e769b97d563b089b9e0ebf8ad361d15076f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90390.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90390"},{"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":"58226942ad3d1423785f815ede5bcc832574f2ea"},{"fixed":"03aad318f0a1f039dddf98739e705fdca3bf0d86"},{"fixed":"6763fb409a0b4106676a52cf934440d9484b32c8"},{"fixed":"cc543e769b97d563b089b9e0ebf8ad361d15076f"},{"fixed":"2911cd0a0f4366a7e06832bc5f0a7fdcc138e4dc"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90390.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90390.json"}}],"schema_version":"1.9.0"}
