Red Hat Product Errata RHSA-2013:1264 0 normal SHIPPED_LIVE Important: kernel-rt security and bug fix update 2013-09-16 21:01:17 UTC

Description Prasad Pandit 2013-06-06 06:56:17 UTC 
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.

Statement:

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

This issue affects the version of the kernel package as shipped with
Red Hat Enterprise MRG 2. Future kernel updates for Red Hat Enterprise MRG 2
