Description GLSAMaker/CVETool Bot gentoo-dev 2015-06-21 13:52:30 UTC 
CVE-2015-0239 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-0239):
  The em_sysenter function in arch/x86/kvm/emulate.c in the Linux kernel
  before 3.18.5, when the guest OS lacks SYSENTER MSR initialization, allows
  guest OS users to gain guest OS privileges or cause a denial of service
  (guest OS crash) by triggering use of a 16-bit code segment for emulation of
  a SYSENTER instruction.
