SUSE Security Update: Security update for the Linux Kernel (Live Patch 21 for
SLE 12 SP2)
______________________________________________________________________________
Announcement ID: SUSE-SU-2019:0683-1
Rating: important
References: #1124729 #1124734 #1128378
Cross-References: CVE-2019-6974 CVE-2019-7221 CVE-2019-9213
Affected Products:
SUSE Linux Enterprise Server for SAP 12-SP2
SUSE Linux Enterprise Server 12-SP2-LTSS
______________________________________________________________________________
An update that fixes three vulnerabilities is now available.
Description:
This update for the Linux Kernel 4.4.121-92_73 fixes several issues.
The following security issues were fixed:
o 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).
o 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).
o 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).

methods like YaST online_update or "zypper patch".
