       An update that fixes four vulnerabilities is now available.
       This update for the Linux Kernel 4.12.14-25_13 fixes several issues.
       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-2019-8912: af_alg_release() in crypto/af_alg.c neglected to set a
         NULL value for a certain structure member, which could have led to a
         use-after-free in sockfs_setattr (bsc#1126284).
       - 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).
