{"id":"CVE-2026-90180","summary":"block: mtip32xx: synchronize ioctls with device removal","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nblock: mtip32xx: synchronize ioctls with device removal\n\nThe ioctl handlers only test REMOVE_PENDING before entering\nmtip_hw_ioctl(). Removal can set that bit immediately afterwards and free\ndd-\u003eport in mtip_hw_exit() while an ioctl still dereferences it. An already\nopen block device can reach the handlers while del_gendisk() is in\nprogress.\n\nSerialize both native and compat ioctls with removal. Set REMOVE_PENDING\nbefore taking the mutex so new callers fail after an in-flight ioctl has\ndrained, and hold the mutex until the port has been torn down.","modified":"2026-09-19T03:47:30.974230947Z","published":"2026-09-17T16:07:05.083Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90180.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/4609e0e0be709e974bec9b52c5022136d25e97d3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/521afbd936ac256b7531470b0b9aa96abf9cd853"},{"type":"WEB","url":"https://git.kernel.org/stable/c/68940f841d013192086a0f6d7cfbac2cd079e228"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8283049aa5fcb4e84b2b2928b2888903bb8ee12e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8a7799597bd683b6bc251fe2edfa9fd1db568a3a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b389dc35a55713ac24a145741e76196fea1663bc"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90180.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90180"},{"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":"88523a61558a040546bf7d8b079ae0755d8e7005"},{"fixed":"521afbd936ac256b7531470b0b9aa96abf9cd853"},{"fixed":"8283049aa5fcb4e84b2b2928b2888903bb8ee12e"},{"fixed":"8a7799597bd683b6bc251fe2edfa9fd1db568a3a"},{"fixed":"4609e0e0be709e974bec9b52c5022136d25e97d3"},{"fixed":"b389dc35a55713ac24a145741e76196fea1663bc"},{"fixed":"68940f841d013192086a0f6d7cfbac2cd079e228"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90180.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.3.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"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-2026-90180.json"}}],"schema_version":"1.9.0"}
