CVE-2017-7184 (GCVE-0-2017-7184)

Vulnerability from cvelistv5 – Published: 2017-03-19 18:00 – Updated: 2024-08-05 15:56
VLAI
Summary
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 4.8.0.41.52.
