Summary
Security update for the Linux Kernel (Live Patch 27 for SLE 12)
Details

This update for the Linux Kernel 3.12.61-52_92 fixes several issues.

The following security issues were fixed:

  • CVE-2018-3646: Local attackers in virtualized guest systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data, even from other virtual machines or the host system (bsc#1099306).
  • CVE-2017-11600: net/xfrm/xfrmpolicy.c did not ensure that the dir value of xfrmuserpolicyid is XFRMPOLICYMAX or less, which allowed local users to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via an XFRMMSG_MIGRATE xfrm Netlink message (bsc#1096564)
  • CVE-2018-10853: A flaw was found in kvm. In which certain instructions such as sgdt/sidt call segmentedwritestd didn't propagate access correctly. As such, during userspace induced exception, the guest can incorrectly assume that the exception happened in the kernel and panic. (bsc#1097108).
