    Security update for the Linux Kernel (Live Patch 23 for SLE 12 SP2)

    This update for the Linux Kernel 4.4.121-92_85 fixes one issue. The following security issue was fixed: - CVE-2018-14734: drivers/infiniband/core/ucma.c allowed ucma_leave_multicast to access a certain data structure after a cleanup step in ucma_process_join, which allows attackers to cause a denial of service (use-after-free) (bsc#1131390).

    Security update for the Linux Kernel (Live Patch 22 for SLE 12 SP2)

    This update for the Linux Kernel 4.4.121-92_80 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

    Security update for the Linux Kernel (Live Patch 25 for SLE 12 SP2)

    This update for the Linux Kernel 4.4.121-92_95 fixes one issue. The following security issue was fixed: - CVE-2018-16884: A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time could make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user could cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bsc#1119947).

    Security update for the Linux Kernel (Live Patch 23 for SLE 12 SP2)

    This update for the Linux Kernel 4.4.121-92_85 fixes one issue. The following security issue was fixed: - CVE-2018-5391: Fixed a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may have caused a denial of service condition by sending specially crafted IP fragments. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size (bsc#1103098).

    Security update for the Linux Kernel (Live Patch 18 for SLE 12 SP2)

    This update for the Linux Kernel 4.4.114-92_64 fixes several issues. The following security issues were fixed: - CVE-2018-17182: The vmacache_flush_all function in mm/vmacache.c mishandled sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations (bsc#1110233). - CVE-2018-14633: A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash
