The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the XFRM subsystem in Linux kernel. A local user with CAP_NET_ADMIN capability can trigger an out-of-bounds read error and read contents of memory on the system.
