The following security issues were fixed:
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 (bsc#1128378).

CVE-2019-7221: Fixed a user-after-free vulnerability in the KVM
 hypervisor related to the emulation of a preemption timer, allowing an
 guest user/process to crash the host kernel. (bsc#1124734).

CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandled
 reference counting because of a race condition, leading to a
 use-after-free (bsc#1124729).

CVE-2018-5391: The Linux kernel was vulnerable to a denial of service
 attack with low rates of specially modified packets targeting IP
 fragment re-assembly. An attacker might have caused a denial of service
 condition by sending specially crafted IP fragments. Various
 vulnerabilities in IP fragmentation have been discovered and fixed over
 the years. The current vulnerability (CVE-2018-5391) became exploitable
 in the Linux kernel with the increase of the IP fragment reassembly
 queue size (bsc#1103098).");
