Description Prasad Pandit 2014-01-15 13:53:18 UTC
Linux kenrel built with the FarSync T-Series driver support(CONFIG_FARSYNC)
is vulnerable to an information leakage flaw. It could occur while doing an
ioctl(SIOCWANDEV) call.

A user/program with CAP_NET_ADMIN privileges could use this flaw to leak kernel memory bytes.

This issue does not affect the versions of the kernel package as shipped with
Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG 2.
