CVE-2023-3106 Information

Description

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.
