kernel-3.10.0-327.22.2.el7

Security issues fixed with this release:

CVE-2015-8767
net/sctp/sm_sideeffect.c in the Linux kernel before 4.3 does not
properly manage the relationship between a lock and a socket, which
allows local users to cause a denial of service (deadlock) via a
crafted sctp_accept call.
CVE-2016-4565
The InfiniBand (aka IB) stack in the Linux kernel before 4.5.3
incorrectly relies on the write system call, which allows local users
to cause a denial of service (kernel memory write operation) or
possibly have unspecified other impact via a uAPI interface.

Security Fixes:
Fixed bugs:

* When Small Computer System Interface (SCSI) devices were removed or deleted, a system crash could occur due to a race condition between listing all SCSI devices and SCSI device removal. The provided patch ensures that the starting node for the klist_iter_init_node() function is actually a member of the list before using it. As a result, a system crash no longer occurs in the described scenario.
* This update offers a reworked series of patches for the resizable hash table (rhashtable) including a number of backported bug fixes and enhancements from upstream.
* Previously, the same value of the mperf Model-Specific Register (MSR) read twice in a row could lead to a kernel panic due to the divide-by-zero error. The provided patch fixes this bug, and the kernel now handles two identical values of mperf gracefully.
* When a transparent proxy application was running and the number of established connections on the computer exceeded one million, unrelated processes, such as curl or ssh, were unable to bind to a local IP on the box to initiate a connection. The provided patch fixes the cooperation of the REUSEADDR/NOREUSEADDR socket option, and thus prevents the local port from being exhausted. As a result, the aforementioned bug no longer occurs in the described scenario.
* Previously, the kernel support for non-local bind for the IPv6 protocol was incomplete. As a consequence, an attempt to bind a socket to an IPv6 address that is not assigned to the host could fail. The provided patch includes changes in the ip_nonlocal_bind variable, which is now set to allow binding to an IPv6 address that is not assigned to the host. As a result, Linux servers are now able to bind to non-local IPv6 addresses as expected.
* On some servers with a faster CPU, USB initialization could previously lead to a kernel hang during boot. If this inconvenience occurred when booting the second kernel during the kdump operation, the kdump service failed and the vmcore was lost. The provided upstream patch fixes this bug, and the kernel no longer hangs after USB initialization.
* Previously, when running iperf servers using the mlx4_en module, a kernel panic occurred. The underlying source code has been fixed, and the kernel panic no longer occurs in the described scenario.
These updated kernel packages include several security issues and numerous bug fixes, some of which you can see below.
