The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * hw: Machine Check Error on Page Size Change * hw: TSX Transaction Asynchronous Abort * Kernel: vhost_net: infinite loop while receiving packets leads to DoS * hw: Intel GPU Denial Of Service while accessing MMIO in lower power state For more details about the security issue, including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section. Bug Fix: * [Intel 6.10 Bug] With mWait/C-states disabled, HT on, ibrs enabled, performance impact observed on user space benchmark * kernel-2.6.32-573.60.2.el6 hangs/resets during boot in efi_enter_virtual_mode on Xeon v2 E7-2870 * Slab leak: skbuff_head_cache slab object still allocated after mcast processes are stopped and quot;fragments dropped after timeoutquot; errors are shown 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5.
