Doc Type: Bug Fix
Doc Text:
A buffer overflow flaw was found in the way the Linux kernel's Intel AES-NI instructions optimized version of the RFC4106 GCM mode decryption functionality handled fragmented packets. A remote attacker could use this flaw to crash, or potentially escalate their privileges on, a system over a connection with an active AES-GCM mode IPSec security association.

Description Prasad Pandit 2015-04-20 10:43:10 UTC 
Linux kernel built with the Intel AES-NI instructions for AES algorithm support
(CONFIG_CRYPTO_AES_NI_INTEL) is vulnerable to a memory corruption issue. It could occur when using the Intel AES-NI instruction to decrypt fragmented network packets.

An unprivileged remote user could use this flaw to crash the system (denial of service) or, potentially, escalate their privileges on a system over a connection with an active AEC-GCM mode IPSec security association.

Comment 1 Prasad Pandit 2015-04-20 10:47:44 UTC 
Statement:

This issue does not affect the version of the kernel package as shipped with
Red Hat Enterprise Linux 5.

This issue affects the versions of Linux kernel as shipped with
Red Hat Enterprise Linux 6, 7 and Red Hat Enterprise MRG 2. Future kernel updates
for Red Hat Enterprise Linux 6 may address this issue.

Is that a typo? Maybe it is supposed to be:

It's not a typo.  RHSA-2015-0981 addresses this vulnerability for the kernel-rt package:

<https://www.redhat.com/archives/rhsa-announce/2015-May/msg00008.html>

Currently, errata pages which document changes to Red Hat Enterprise Linux 7 only (and not other versions of Red Hat Enterprise Linux) do not appear under rhn.redhat.com URLs.
Comment 18 David Eisenstein 2015-06-07 22:03:01 UTC 
Doesn't this bug also affect RHEL 6 kernel?  I see the same error lines in 
arch/x86/crypto/aesni-intel_glue.c in kernel version kernel-2.6.32-504.16.2.el6 .
