{"id":"CVE-2026-46327","summary":"dm: fix unlocked test for dm_suspended_md","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndm: fix unlocked test for dm_suspended_md\n\nThe function dm_blk_report_zones tests if the device is suspended with\nthe \"dm_suspended_md\" call. However, this function is called without\nholding any locks, so the device may be suspended just after it.\n\nMove the call to dm_suspended_md after dm_get_live_table, so that the\ndevice can't be suspended after the suspended state was tested.","modified":"2026-10-28T02:30:28.676697072Z","published":"2026-06-09T12:25:54.781Z","related":["SUSE-SU-2026:23066-1","SUSE-SU-2026:23068-1","SUSE-SU-2026:23221-1","SUSE-SU-2026:23231-1","SUSE-SU-2026:23237-1","openSUSE-SU-2026:21555-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46327.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/175ac0a6115400278d3900f5a04a58b17b3f6cd0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/24c405fdbe215c45e57bba672cc42859038491ee"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7a3385e97af2b6f485fef11e82d8c29adee4be93"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d809a36692ee1394cac85ce6ba7cf8ea58da5812"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46327.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46327"},{"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":"f9c1bdf24615303d48a2d0fd629c88f3189563aa"},{"fixed":"175ac0a6115400278d3900f5a04a58b17b3f6cd0"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"37f53a2c60d03743e0eacf7a0c01c279776fef4e"},{"fixed":"7a3385e97af2b6f485fef11e82d8c29adee4be93"},{"fixed":"d809a36692ee1394cac85ce6ba7cf8ea58da5812"},{"fixed":"24c405fdbe215c45e57bba672cc42859038491ee"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.12.34"},{"fixed":"6.12.75"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.15.3"},{"fixed":"6.16"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"d19bc1b4dd5f322980b1f05f79b2ea4f0db10920"}]}],"versions":["v6.12.74","v6.12.73","v6.12.72","v6.12.71","v6.12.70","v6.12.69","v6.12.68","v6.12.67","v6.12.66","v6.12.65","v6.12.64","v6.12.63","v6.12.62","v6.12.61","v6.12.60","v6.12.59","v6.12.58","v6.12.57","v6.12.56","v6.12.55","v6.12.54","v6.12.53","v6.12.52","v6.12.51","v6.12.50","v6.12.49","v6.12.48","v6.12.47","v6.12.46","v6.12.45","v6.12.44","v6.12.43","v6.12.42","v6.12.41","v6.12.40","v6.12.39","v6.12.38","v6.12.37","v6.12.36","v6.12.35","v6.12.34","v6.15.11","v6.15.10","v6.15.9","v6.15.8","v6.15.7","v6.15.6","v6.15.5","v6.15.4","v6.15.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46327.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.75"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.14"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.16.0"},{"fixed":"6.19.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46327.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
