== Changes ==
Since {{kernel link|rhel6-testing|042stab114.5}}:

* Rebase to RHEL6 kernel 2.6.32-573.26.1.el6 (security, bug fixes, and enhancements)
* A flaw was found in the way the Linux kernel handled IRET faults during the processing of NMIs. An unprivileged, local user could use this flaw to crash the system or, potentially (although highly unlikely), escalate their privileges on the system. (CVE-2015-5157)
* A race condition flaw was found in the way the Linux kernel's SCTP implementation handled sctp_accept() during the processing of heartbeat timeout events. A remote attacker could use this flaw to prevent further connections to be accepted by the SCTP server running on the system, resulting in a denial of service. (CVE-2015-8767)
* NFS client with kernels 2.6.32-573.10.2.el6 or above could hang with 'not responding, still trying' messages and running processes in spinlock. (https://access.redhat.com/solutions/2215491)
* Network devices that used the mainline veth driver did not check TCP checksums. (https://access.redhat.com/solutions/2216661)
** vethX interfaces of OpenVZ and VZ containers are not affected as they use a different driver. The affected veth driver was used inside Docker-ready containers or could be used by host admin for their own purposes.
* Warning at drivers/block/ploop/io_direct_map.c:841 trim_extent_mappings. (PSBM-45999)
* LDT entries were incorrectly restored from CPT image. (OVZ-6228)
* some internal fixes
