Linux Kernel CVE-2017-7184 Local Privilege Escalation Vulnerability

Description: The xfrm_replay_verify_len function in net/xfrm/xfrm_user.c in the Linux kernel through 4.10.6 does not validate certain size data after an XFRM_MSG_NEWAE update, which allows local users to obtain root privileges or cause a denial of service (heap-based out-of-bounds access) by leveraging the CAP_NET_ADMIN capability, as demonstrated during a Pwn2Own competition at CanSecWest 2017 for the Ubuntu 16.10 linux-image-* package

Impact: Local attackers may exploit this issue to gain root privileges. Linux Kernel version 4.8 is vulnerable; other versions may also be affected.

Mitigation: Updates are available. Please check specific vendor advisory for more information.
