{"id":"CVE-2023-39192","details":"A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds read by setting the size fields with a value beyond the array boundaries, leading to a crash or information disclosure.","modified":"2026-03-13T07:40:37.944768Z","published":"2023-10-09T18:15:10.233Z","related":["SUSE-SU-2023:4031-1","SUSE-SU-2023:4032-1","SUSE-SU-2023:4033-1","SUSE-SU-2023:4035-1","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-2023:4347-1","SUSE-SU-2023:4348-1","SUSE-SU-2023:4358-1","SUSE-SU-2023:4377-1","SUSE-SU-2024:0112-1","openSUSE-SU-2024:13305-1","openSUSE-SU-2024:13704-1"],"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:3138"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2023-39192"},{"type":"ADVISORY","url":"https://www.zerodayinitiative.com/advisories/ZDI-CAN-18408/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:2950"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2226784"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"6.6"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0"}]},{"events":[{"introduced":"0"},{"last_affected":"38"}]}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-39192.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:H"}]}
