Description Agostino Sarubbo gentoo-dev 2013-03-07 11:46:40 UTC
From $URL :

Linux kernels built with crypto user APIs are vulnerable to the information
disclosure flaw. It occurs when user calls the `crypto_*_report' APIs via
netlink based crypto API interface.

A privileged user/program (CAP_NET_ADMIN) could use this flaw to read kernel memory area.
