gpp_maybe Security update for the linux kernel (live patch 15 for sle 12 sp3)

SUSE-SLE-Live-Patching-12-SP3-2019-751

This update for the Linux Kernel 4.4.140-94_42 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-2019-7221: 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).
