{"id":"CVE-2023-39198","details":"A race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a use-after-free issue, potentially leading to a denial of service or privilege escalation.","modified":"2026-03-14T14:54:35.224871Z","published":"2023-11-09T20:15:08.730Z","related":["ALSA-2024:2394","SUSE-SU-2023:4730-1","SUSE-SU-2023:4731-1","SUSE-SU-2023:4732-1","SUSE-SU-2023:4733-1","SUSE-SU-2023:4734-1","SUSE-SU-2023:4735-1","SUSE-SU-2023:4782-1","SUSE-SU-2023:4783-1","SUSE-SU-2023:4784-1","SUSE-SU-2023:4810-1","SUSE-SU-2023:4811-1","SUSE-SU-2023:4882-1","SUSE-SU-2023:4883-1","SUSE-SU-2024:0622-1","SUSE-SU-2024:0655-1","SUSE-SU-2024:0662-1","SUSE-SU-2024:0666-1","SUSE-SU-2024:0698-1","SUSE-SU-2024:0705-1","SUSE-SU-2024:0727-1"],"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00016.html"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:2394"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:2950"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:3138"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2023-39198"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2218332"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"6.5"}]},{"events":[{"introduced":"0"},{"last_affected":"6.5-rc1"}]},{"events":[{"introduced":"0"},{"last_affected":"6.5-rc2"}]},{"events":[{"introduced":"0"},{"last_affected":"6.5-rc3"}]},{"events":[{"introduced":"0"},{"last_affected":"6.5-rc4"}]},{"events":[{"introduced":"0"},{"last_affected":"6.5-rc5"}]},{"events":[{"introduced":"0"},{"last_affected":"6.5-rc6"}]},{"events":[{"introduced":"0"},{"last_affected":"38"}]},{"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-2023-39198.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}
