- Summary
- Security update for the Linux Kernel (Live Patch 25 for SLE 12 SP2)
- Details
-
This update for the Linux Kernel 4.4.121-92_95 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: kvmioctlcreatedevice in virt/kvm/kvmmain.c mishandled reference counting because of a race condition, leading to a use-after-free (bsc#1124729).
