SUSE Security Update: Security update for the Linux Kernel (Live Patch 8 for SLE 15) ______________________________________________________________________________ Announcement ID: SUSE-SU-2019:0845-1 Rating: important References: #1124729 #1124734 #1126284 #1128378 Cross-References: CVE-2019-6974 CVE-2019-7221 CVE-2019-8912 CVE-2019-9213 Affected Products: SUSE Linux Enterprise Module for Live Patching 15 ______________________________________________________________________________ An update that fixes four vulnerabilities is now available. Description: This update for the Linux Kernel 4.12.14-25_28 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).
