Beschreibung:	Summary: The remote host is missing an update for the 'kernel' package(s) announced via the referenced advisory. Vulnerability Insight: The openSUSE Leap 42.3 kernel was updated to 4.4.90 to receive various security and bugfixes. The following security bugs were fixed: - CVE-2017-1000252: The KVM subsystem in the Linux kernel allowed guest OS users to cause a denial of service (assertion failure, and hypervisor hang or crash) via an out-of bounds guest_irq value, related to arch/x86/kvm/vmx.c and virt/kvm/eventfd.c (bnc#1058038). - CVE-2017-14489: The iscsi_if_rx function in drivers/scsi/scsi_transport_iscsi.c in the Linux kernel allowed local users to cause a denial of service (panic) by leveraging incorrect length validation (bnc#1059051). - CVE-2017-12153: A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux kernel This function did not check whether the required attributes are present in a Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in a NULL pointer dereference and system crash (bnc#1058410). - CVE-2017-12154: The prepare_vmcs02 function in arch/x86/kvm/vmx.c in the Linux kernel did not ensure that the 'CR8-load exiting' and 'CR8-store exiting' L0 vmcs02 controls exist in cases where L1 omits the 'use TPR shadow' vmcs12 control, which allowed KVM L2 guest OS users to obtain read and write access to the hardware CR8 register (bnc#1058507). The following non-security bugs were fixed: - arc: Re-enable MMU upon Machine Check exception (bnc#1012382). - arm64: fault: Route pte translation faults via do_translation_fault (bnc#1012382). - arm64: Make sure SPsel is always set (bnc#1012382). - arm: pxa: add the number of DMA requestor lines (bnc#1012382). - arm: pxa: fix the number of DMA requestor lines (bnc#1012382). - bcache: correct cache_dirty_target in __update_writeback_rate() (bnc#1012382). - bcache: Correct return value for sysfs attach errors (bnc#1012382). - bcache: do not subtract sectors_to_gc for bypassed IO (bnc#1012382). - bcache: fix bch_hprint crash and improve output (bnc#1012382). - bcache: fix for gc and write-back race (bnc#1012382). - bcache: Fix leak of bdev reference (bnc#1012382). - bcache: initialize dirty stripes in flash_dev_run() (bnc#1012382). - block: Relax a check in blk_start_queue() (bnc#1012382). - bsg-lib: do not free job in bsg_prepare_job (bnc#1012382). - btrfs: change how we decide to commit transactions during flushing (bsc#1060197). - btrfs: fix NULL pointer dereference from free_reloc_roots() (bnc#1012382). - btrfs: prevent to set invalid default subvolid (bnc#1012382). - btrfs ...
