Affected Products:
openSUSE Leap 42.2

An update that solves four vulnerabilities and has 15 fixes
is now available.


The openSUSE Leap 42.2 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).
