{"id":"CVE-2025-22125","summary":"md/raid1,raid10: don't ignore IO flags","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmd/raid1,raid10: don't ignore IO flags\n\nIf blk-wbt is enabled by default, it's found that raid write performance\nis quite bad because all IO are throttled by wbt of underlying disks,\ndue to flag REQ_IDLE is ignored. And turns out this behaviour exist since\nblk-wbt is introduced.\n\nOther than REQ_IDLE, other flags should not be ignored as well, for\nexample REQ_META can be set for filesystems, clearing it can cause priority\nreverse problems; And REQ_NOWAIT should not be cleared as well, because\nio will wait instead of failing directly in underlying disks.\n\nFix those problems by keep IO flags from master bio.\n\nFises: f51d46d0e7cb (\"md: add support for REQ_NOWAIT\")","modified":"2026-04-02T12:45:21.546589Z","published":"2025-04-16T14:13:08.779Z","related":["SUSE-SU-2025:01919-1","SUSE-SU-2025:01951-1","SUSE-SU-2025:01964-1","SUSE-SU-2025:01965-1","SUSE-SU-2025:01967-1","SUSE-SU-2025:01972-1","SUSE-SU-2025:02000-1","SUSE-SU-2025:20408-1","SUSE-SU-2025:20413-1","SUSE-SU-2025:20419-1","SUSE-SU-2025:20421-1","SUSE-SU-2026:1078-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/22xxx/CVE-2025-22125.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/73506e581c0b1814cdfd2229d589f30751d7de26"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8a0adf3d778c4a0893c6d34a9e1b0082a6f1c495"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e879a0d9cb086c8e52ce6c04e5bfa63825a6213c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/22xxx/CVE-2025-22125.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-22125"},{"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":"5404bc7a87b9949cf61e0174b21f80e73239ab25"},{"fixed":"73506e581c0b1814cdfd2229d589f30751d7de26"},{"fixed":"8a0adf3d778c4a0893c6d34a9e1b0082a6f1c495"},{"fixed":"e879a0d9cb086c8e52ce6c04e5bfa63825a6213c"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-22125.json"}}],"schema_version":"1.7.5"}
