{"id":"CVE-2023-3106","details":"A NULL pointer dereference vulnerability was found in netlink_dump. This issue can occur when the Netlink socket receives the message(sendmsg) for the XFRM_MSG_GETSA, XFRM_MSG_GETPOLICY type message, and the DUMP flag is set and can cause a denial of service or possibly another unspecified impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is unlikely.","modified":"2026-03-14T12:05:06.612928Z","published":"2023-07-12T09:15:14.550Z","related":["SUSE-SU-2023:3324-1"],"references":[{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2023-3106"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2221501"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/1ba5bf993c6a3142e18e68ea6452b347f9cb5635"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-3106.json","unresolved_ranges":[{"events":[{"introduced":"3.15"},{"fixed":"3.16.39"}]},{"events":[{"introduced":"3.17"},{"fixed":"4.4.223"}]},{"events":[{"introduced":"4.5"},{"fixed":"4.7.10"}]},{"events":[{"introduced":"0"},{"last_affected":"4.8-rc1"}]},{"events":[{"introduced":"0"},{"last_affected":"4.8-rc2"}]},{"events":[{"introduced":"0"},{"last_affected":"4.8-rc3"}]},{"events":[{"introduced":"0"},{"last_affected":"4.8-rc4"}]},{"events":[{"introduced":"0"},{"last_affected":"4.8-rc5"}]},{"events":[{"introduced":"0"},{"last_affected":"4.8-rc6"}]},{"events":[{"introduced":"0"},{"last_affected":"38"}]}]}}],"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"}]}
