Description Prasad J Pandit 2013-06-06 02:56:17 EDT
Linux kernel built with the Filesystem wide access notification
(CONFIG_FANOTIFY) support is vulnerable to an information leakage
flaw. The leaked bytes could be accessed via read(2) call on the
fanotify descriptor.

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

Red Hat Enterprise Linux 5 and Red Hat Enterprise Linux 6.

This issue affects the version of the kernel package as shipped with
