{"id":"CVE-2023-3390","details":"A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c.\n\nMishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue.\n\nWe recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97.","modified":"2026-04-15T23:59:39.602496598Z","published":"2023-06-28T21:15:10.447Z","related":["ALSA-2023:5069","ALSA-2023:5091","ALSA-2023:5244","SUSE-SU-2023:3171-1","SUSE-SU-2023:3172-1","SUSE-SU-2023:3180-1","SUSE-SU-2023:3182-1","SUSE-SU-2023:3302-1","SUSE-SU-2023:3318-1","SUSE-SU-2023:3390-1","SUSE-SU-2023:3391-1","SUSE-SU-2023:3421-1","SUSE-SU-2023:4166-1","SUSE-SU-2023:4175-1","SUSE-SU-2023:4201-1","SUSE-SU-2023:4219-1","SUSE-SU-2023:4239-1","SUSE-SU-2023:4245-1","SUSE-SU-2023:4267-1","SUSE-SU-2023:4279-1","SUSE-SU-2023:4285-1","SUSE-SU-2023:4308-1","SUSE-SU-2023:4326-1"],"references":[{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20230818-0004/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2023/dsa-5448"},{"type":"ADVISORY","url":"https://www.debian.org/security/2023/dsa-5461"},{"type":"ADVISORY","url":"http://packetstormsecurity.com/files/174577/Kernel-Live-Patch-Security-Notice-LSN-0097-1.html"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2023/08/msg00001.html"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html"},{"type":"FIX","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=1240eb93f0616b21c675416516ff3d74798fdc97"},{"type":"FIX","url":"https://kernel.dance/1240eb93f0616b21c675416516ff3d74798fdc97"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-3390.json","unresolved_ranges":[{"events":[{"introduced":"3.16"},{"fixed":"4.14.322"}]},{"events":[{"introduced":"4.15"},{"fixed":"4.19.291"}]},{"events":[{"introduced":"4.20"},{"fixed":"5.4.251"}]},{"events":[{"introduced":"5.5"},{"fixed":"5.10.188"}]},{"events":[{"introduced":"5.11"},{"fixed":"5.15.118"}]},{"events":[{"introduced":"5.16"},{"fixed":"6.1.35"}]},{"events":[{"introduced":"6.2"},{"fixed":"6.3.9"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
