   An update that solves 6 vulnerabilities and has 21 fixes is
   now available.

Description:



   The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated to receive
   various security and bugfixes.

   The following security bugs were fixed:

   - CVE-2019-2024: A use-after-free when disconnecting a source was fixed
     which could lead to crashes. bnc#1129179).
   - CVE-2019-9213: expand_downwards in mm/mmap.c lacked a check for the mmap
     minimum address, which made it easier for attackers to exploit kernel
     NULL pointer dereferences on non-SMAP platforms. This is related to a
     capability check for the wrong task (bnc#1128166).
   - CVE-2018-14633: A security flaw was found in the
     chap_server_compute_md5() function in the ISCSI target code in the Linux
     kernel in a way an authentication request from an ISCSI initiator is
     processed. (bnc#1107829).
   - CVE-2019-7221: The KVM implementation in the Linux kernel had a
     Use-after-Free (bnc#1124732).
   - CVE-2019-7222: The KVM implementation in the Linux kernel had an
     Information Leak (bnc#1124735).
   - CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandled
     reference counting because of a race condition, which led to a
     use-after-free (bnc#1124728).

   The following non-security bugs were fixed:

   - copy_mount_string: Limit string length to PATH_MAX (bsc#1082943).
   - enic: add wq clean up budget (bsc#1075697, bsc#1120691. bsc#1102959).
   - ibmvscsi: Fix empty event pool access during host removal (bsc#1119019).
   - ipv4: ipv6: Adjust the frag mem limit after truesize has been changed
     (bsc#1110286).
   - kmps: obsolete older KMPs of the same flavour (bsc#1127155, bsc#1109137).
   - netfilter: ipv6: Adjust the frag mem limit after truesize has been
     changed (bsc#1110286).
   - perf/x86: Add sysfs entry to freeze counters on SMI (bsc#1121805).
   - perf/x86/intel: Delay memory deallocation until x86_pmu_dead_cpu()
     (bsc#1121805).
   - perf/x86/intel: Do not enable freeze-on-smi for PerfMon V1 (bsc#1121805).
   - perf/x86/intel: Fix memory corruption (bsc#1121805).
   - perf/x86/intel: Generalize dynamic constraint creation (bsc#1121805).
   - perf/x86/intel: Implement support for TSX Force Abort (bsc#1121805).
   - perf/x86/intel: Make cpuc allocations consistent (bsc#1121805).
   - pseries/energy: Use OF accessor function to read ibm,drc-indexes
     (bsc#1129080).
   - restore cond_resched() in shrink_dcache_parent() (bsc#1098599,
     bsc#1105402, bsc#1127758).
   - rps: flow_dissector: Fix uninitialized flow_keys used in __skb_get_hash
     possibly (bsc#1108145).
   - scsi: megaraid_sas: Send SYNCHRONIZE_CACHE for VD to firmware
     (bsc#1121698).
   - scsi: sym53c8xx: fix NULL pointer dereference panic in sym_int_sir()
     (bsc#1125315).
   - x86: Add TSX Force Abort CPUID/MSR (bsc#1121805).
   - x86: respect memory size limiting via mem= parameter (bsc#1117645).
   - x86/spectre_v2: Do not check microcode versions when running under
     hypervisors (bsc#1122821).
   - x86/xen: dont add memory above max allowed allocation (bsc#1117645).
   - xen-netfront: Fix hang on device removal (bnc#1012382).
   - xfrm: use complete IPv6 addresses for hash (bsc#1109330).
   - xfs: remove filestream item xfs_inode reference (bsc#1127961).
