This\nfix is based on the assumption that scsi_host_busy() and\nscsi_mq_setup_tags() calls are serialized. This is the case in the UFS\ndriver.","modified":"2026-04-16T00:11:03.302126980Z","published":"2025-12-16T13:57:17.541Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68224.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/143257917b836bd5fc434063030fda199e249624"},{"type":"WEB","url":"https://git.kernel.org/stable/c/47c8b35a1f1d53aac156480cea0a0c5c82919f03"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5d778778b40bcdfd9f8817fea1ec6ebcbec69c0a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/804b5b8e3545445450387ae6891262c421c49304"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a0b7780602b1b196f47e527fec82166a7e67c4d0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d579f496681c5136d63cb4fbb685511227e73602"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e208fb1660c4a43f06b7b66c3ff22dde84ec3990"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68224.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68224"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2"},{"fixed":"143257917b836bd5fc434063030fda199e249624"},{"fixed":"804b5b8e3545445450387ae6891262c421c49304"},{"fixed":"d579f496681c5136d63cb4fbb685511227e73602"},{"fixed":"5d778778b40bcdfd9f8817fea1ec6ebcbec69c0a"},{"fixed":"47c8b35a1f1d53aac156480cea0a0c5c82919f03"},{"fixed":"e208fb1660c4a43f06b7b66c3ff22dde84ec3990"},{"fixed":"a0b7780602b1b196f47e527fec82166a7e67c4d0"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-68224.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.247"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.197"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.159"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.118"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.60"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.17.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-68224.json"}}],"schema_version":"1.7.5"}
