The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * kernel: double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c * kernel: use-after-free in __blk_add_trace in kernel/trace/blktrace.c * Kernel: NetLabel: null pointer dereference while receiving CIPSO packet with null category may cause kernel panic 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: * Delay in RT task scheduled. Incorrect nr_scheduled value. * ixgbevf interface goes down on hypervisor and causes outage * kernel: UAF in cdev_put when a PTP device is removed while its chardev is open * [HPEMC RHEL 7.7 RHEL 7.8 REGRESSION] kernel not populating numa_nod in /sys/devices... for PMEM * Unable to exclude files from auditing * DNAT"d packet is not unmangled upon reply on openshift node * top shows super high loads when tuned profile realtime-virtual-host is applied * [RHEL 7.9] mdraid devices do not autocorrect read errors on parity blocks * Observed a memory leak while using dm-multipath * RHEL7.8: megaraid_sas: MSIx allocation fails in resume path * Backport: Guest microcode version mismatch on secondary processors * dm-multipath high load backport incorrect * qla2xxx: Urgent driver fix needed. Initiator does not relogin to target after receiving an explicit logout * Potential deadlock in iscsi_if_rx func * High iSCSI read latency resolved by "tcp: implement coalescing on backlog queue" * kdump: crashkernel=xM,low is likely to fail when x is big enough * [RHEL7.8][Azure]Commits to resolve high network latency * net_sched: remove a bogus warning in hfsc * NETDEV WATCHDOG: enp3s0 : transmit queue 0 timed out * BUG: unable to handle kernel NULL pointer dereference at fl_dump * [ Marvell 7.9] update qla2xxx driver with critical bug fixes
