"Security Fix(es) :

  - Kernel: KVM: OOB memory access via mmio ring buffer
    (CVE-2019-14821)

  - kernel: local attacker can trigger multiple
    use-after-free conditions results in privilege
    escalation (CVE-2019-15239)

Bug Fix(es) :

  - On SL 7.7 kernel SCSI VPD information for NVMe drives is
    missing (breaks InfoScale)

  - SL7 fnic spamming logs: Current vnic speed set to :
    40000

  - kernel build: parallelize redhat/mod-sign.sh

  - kernel build: speed up module compression step

  - Nested VirtualBox VMs on Windows guest has the potential
    of impacting memory region allocated to other KVM guests

  - NULL pointer dereference at check_preempt_wakeup+0x109

  - Regression: panic in pick_next_task_rt

  - ixgbe reports 'Detected Tx Unit Hang' with adapter reset
    on SL 7

  - [Intel 7.8 Bug] [KVM][CLX]
    CPUID_7_0_EDX_ARCH_CAPABILITIES is not enabled in VM.

  - nvme: dead loop in
    blk_mq_tagset_wait_completed_request() when it is called
    from timeout handler

  - [mlx5] VF Representer naming is not
    consistent/persistent through reboots with OSPD
    deployment

  - OS getting restarted because of driver issue with QLogic
    Corp. ISP2532-based 8Gb Fibre Channel to PCI Express HBA
    [1077:2532] (rev 02).

  - mlx5: Load balancing not working over VF LAG
    configuration

  - SL7.8 - ISST-LTE: vimlp1: Running LTP af_alg04.c
    (crypto) crash the LPAR

  - SL7.5 - Fix security issues on crypto vmx

  - SL 7.7 RC1 - Host crashes about 4.5 hours into switch
    port bounce test

  - SL7.6 - cacheinfo code unsafe vs LPM

  - xfs hangs on acquiring xfs_buf semaphore

  - single CPU VM hangs during open_posix_testsuite

  - rcu_sched self-detected stall on CPU while booting with
    nohz_full");
