{"id":"CVE-2022-49376","summary":"scsi: sd: Fix potential NULL pointer dereference","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: sd: Fix potential NULL pointer dereference\n\nIf sd_probe() sees an early error before sdkp-\u003edevice is initialized,\nsd_zbc_release_disk() is called. This causes a NULL pointer dereference\nwhen sd_is_zoned() is called inside that function. Avoid this by removing\nthe call to sd_zbc_release_disk() in sd_probe() error path.\n\nThis change is safe and does not result in zone information memory leakage\nbecause the zone information for a zoned disk is allocated only when\nsd_revalidate_disk() is called, at which point sdkp-\u003edisk_dev is fully set,\nresulting in sd_disk_release() being called when needed to cleanup a disk\nzone information using sd_zbc_release_disk().","modified":"2026-04-02T08:27:32.167820Z","published":"2025-02-26T02:11:16.118Z","related":["SUSE-SU-2025:1027-1","SUSE-SU-2025:1176-1","SUSE-SU-2025:1183-1","SUSE-SU-2025:1194-1","SUSE-SU-2025:1241-1","SUSE-SU-2025:1263-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49376.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/05fbde3a77a4f1d62e4c4428f384288c1f1a0be5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0fcb0b131cc90c8f523a293d84c58d0c7273c96f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3733439593ad12f7b54ae35c273ea6f15d692de3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/78f8e96df06e2d04d82d4071c299b59d28744f47"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c1f0187025905e9981000d44a92e159468b561a8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49376.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49376"},{"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":"89d9475610771b5e5fe1879075f0fc9ba6e3755f"},{"fixed":"c1f0187025905e9981000d44a92e159468b561a8"},{"fixed":"0fcb0b131cc90c8f523a293d84c58d0c7273c96f"},{"fixed":"78f8e96df06e2d04d82d4071c299b59d28744f47"},{"fixed":"3733439593ad12f7b54ae35c273ea6f15d692de3"},{"fixed":"05fbde3a77a4f1d62e4c4428f384288c1f1a0be5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-49376.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
