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
