{"id":"CVE-2023-1192","details":"A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a denial of service.","modified":"2026-03-14T11:57:41.038590Z","published":"2023-11-01T20:15:08.597Z","related":["ALSA-2023:7549","SUSE-SU-2023:3988-1","SUSE-SU-2023:4028-1","SUSE-SU-2023:4030-1","SUSE-SU-2023:4031-1","SUSE-SU-2023:4032-1","SUSE-SU-2023:4033-1","SUSE-SU-2023:4057-1","SUSE-SU-2023:4058-1","SUSE-SU-2023:4071-1","SUSE-SU-2023:4072-1","SUSE-SU-2023:4072-2","SUSE-SU-2023:4093-1","SUSE-SU-2023:4095-1","SUSE-SU-2023:4142-1","SUSE-SU-2023:4347-1","SUSE-SU-2024:1454-1","SUSE-SU-2024:1489-1","SUSE-SU-2025:0833-1","SUSE-SU-2025:0833-2","SUSE-SU-2025:0835-1","SUSE-SU-2025:0853-1","SUSE-SU-2025:0945-1","openSUSE-SU-2024:13305-1","openSUSE-SU-2024:13704-1"],"references":[{"type":"WEB","url":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d527f51331cace562393a8038d870b3e9916686f"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2023-1192"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2154178"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"6.4"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0"}]},{"events":[{"introduced":"0"},{"last_affected":"9.0"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-1192.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
