Security update for the Linux Kernel (Live Patch 20 for SLE 12 SP2) (Important)
Description:
This update for the Linux Kernel 4.4.120-92_70 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).
