https://notcve.org/view.php?id=CVE-2023-3106
12 Jul 2023 — 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. • https://access.redhat.com/security/cve/CVE-2023-3106 • CWE-476: NULL Pointer Dereference •
