- Details

The xfrmreplayverifylen function in net/xfrm/xfrmuser.c in the Linux kernel through 4.10.6 does not validate certain size data after an XFRMMSGNEWAE update, which allows local users to obtain root privileges or cause a denial of service (heap-based out-of-bounds access) by leveraging the CAPNETADMIN capability, as demonstrated during a Pwn2Own competition at CanSecWest 2017 for the Ubuntu 16.10 linux-image-* package 4.8.0.41.52.
