"An update for kernel-rt is now available for Red Hat Enterprise MRG 2.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The kernel-rt packages provide the Real Time Linux Kernel, which
enables fine-tuning for systems with extremely high determinism
requirements.

Security Fix(es) :

* Out-of-bounds kernel heap access vulnerability was found in xfrm,
kernel's IP framework for transforming packets. An error dealing with
netlink messages from an unprivileged user leads to arbitrary
read/write and privilege escalation. (CVE-2017-7184, Important)

* A race condition issue leading to a use-after-free flaw was found in
the way the raw packet sockets are implemented in the Linux kernel
networking subsystem handling synchronization. A local user able to
open a raw packet socket (requires the CAP_NET_RAW capability) could
use this flaw to elevate their privileges on the system.
(CVE-2017-1000111, Important)

* An exploitable memory corruption flaw was found in the Linux kernel.
The append path can be erroneously switched from UFO to non-UFO in
ip_ufo_append_data() when building an UFO packet with MSG_MORE option.
If unprivileged user namespaces are available, this flaw can be
exploited to gain root privileges. (CVE-2017-1000112, Important)

* Kernel memory corruption due to a buffer overflow was found in
brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to
v4.13-rc1. The vulnerability can be triggered by sending a crafted
NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be
triggered remotely as certain userspace code is needed for this. An
unprivileged local user could use this flaw to induce kernel memory
corruption on the system, leading to a crash. Due to the nature of the
flaw, privilege escalation cannot be fully ruled out, although it is
unlikely. (CVE-2017-7541, Moderate)

* An integer overflow vulnerability in ip6_find_1stfragopt() function
was found. A local attacker that has privileges (of CAP_NET_RAW) to
open raw socket can cause an infinite loop inside the
ip6_find_1stfragopt() function. (CVE-2017-7542, Moderate)

* A kernel data leak due to an out-of-bound read was found in the
Linux kernel in inet_diag_msg_sctp{,l}addr_fill() and
sctp_get_sctp_info() functions present since version 4.7-rc1 through
version 4.13. A data leak happens when these functions fill in
sockaddr data structures used to export socket's diagnostic
information. As a result, up to 100 bytes of the slab data could be
leaked to a userspace. (CVE-2017-7558, Moderate)

* The mq_notify function in the Linux kernel through 4.11.9 does not
set the sock pointer to NULL upon entry into the retry logic. During a
user-space close of a Netlink socket, it allows attackers to possibly
cause a situation where a value may be used after being freed
(use-after-free) which may lead to memory corruption or other
unspecified other impact. (CVE-2017-11176, Moderate)

* A divide-by-zero vulnerability was found in the __tcp_select_window
function in the Linux kernel. This can result in a kernel panic
causing a local denial of service. (CVE-2017-14106, Moderate)

* A flaw was found where the XFS filesystem code mishandles a
user-settable inode flag in the Linux kernel prior to 4.14-rc1. This
can cause a local denial of service via a kernel panic.
(CVE-2017-14340, Moderate)

Red Hat would like to thank Chaitin Security Research Lab for
reporting CVE-2017-7184; Willem de Bruijn for reporting
CVE-2017-1000111; and Andrey Konovalov for reporting CVE-2017-1000112.
The CVE-2017-7558 issue was discovered by Stefano Brivio (Red Hat) and
the CVE-2017-14340 issue was discovered by Dave Chinner (Red Hat).

Bug Fix(es) :

* kernel-rt packages have been upgraded to the 3.10.0-693.5.2 source
tree, which provides number of bug fixes over the previous version.
