{"id":"CVE-2023-42754","details":"A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was assumed to be associated with a device before calling __ip_options_compile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash the system.","modified":"2026-04-16T04:37:07.258325232Z","published":"2023-10-05T19:15:11.413Z","related":["ALSA-2024:2394","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","USN-6537-1","USN-6573-1","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":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GISYSL3F6WIEVGHJGLC2MFNTUXHPTKQH/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GPMICQ2HVZO5UAM5KPXHAZKA2U3ZDOO6/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/V5PDNWPKAP3WL5RQZ4RIDS6MG32OHH5R/"},{"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":"FIX","url":"https://access.redhat.com/security/cve/CVE-2023-42754"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2239845"},{"type":"FIX","url":"https://seclists.org/oss-sec/2023/q4/14"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"6.6"}]},{"events":[{"introduced":"0"},{"last_affected":"6.6-rc1"}]},{"events":[{"introduced":"0"},{"last_affected":"6.6-rc2"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0"}]},{"events":[{"introduced":"0"},{"last_affected":"9.0"}]},{"events":[{"introduced":"0"},{"last_affected":"37"}]},{"events":[{"introduced":"0"},{"last_affected":"38"}]},{"events":[{"introduced":"0"},{"last_affected":"39"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-42754.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"}]}
