The following security issues were fixed:
- CVE-2018-3646: Local attackers in virtualized guest systems could use
 speculative code patterns on hyperthreaded processors to read data
 present in the L1 Datacache used by other hyperthreads on the same CPU
 core, potentially leaking sensitive data, even from other virtual
 machines or the host system (bsc#1099306).
- CVE-2017-11600: net/xfrm/xfrm_policy.c did not ensure that the dir value
 of xfrm_userpolicy_id is XFRM_POLICY_MAX or less, which allowed local
 users to cause a denial of service (out-of-bounds access) or possibly
 have unspecified other impact via an XFRM_MSG_MIGRATE xfrm Netlink
 message (bsc#1096564)
- CVE-2018-10853: A flaw was found in kvm. In which certain instructions
 such as sgdt/sidt call segmented_write_std didn't propagate access
 correctly. As such, during userspace induced exception, the guest can
 incorrectly assume that the exception happened in the kernel and panic.
