CVE-2023-3106

Kernel: netlink socket crash (null pointer deref) in netlink_dump function

Published: 7/12/2023 Last updated: 2/7/2025 Reserved: 6/5/2023

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.
