CVE-2015-5307 (retired)

Priority
Description
The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through
4.6.x, allows guest OS users to cause a denial of service (host OS panic or
hang) by triggering many #AC (aka Alignment Check) exceptions, related to
svm.c and vmx.c.
Ubuntu-Description
Ben Serebrin discovered that the KVM hypervisor implementation in the Linux
kernel did not properly catch Alignment Check exceptions. An attacker in a
guest virtual machine could use this to cause a denial of service (system
crash) in the host OS.
Notes
 jdstrand> android kernels (flo, goldfish, grouper, maguro, mako and manta) are
  not supported on the Ubuntu Touch 14.10 and earlier preview kernels
 jdstrand> linux-lts-saucy no longer receives official support
 jdstrand> linux-lts-quantal no longer receives official support
 sbeattie> affects x86 kernels only
 sbeattie> fixed in upstream 54a20552e1eae07aa240fa370a0293e006b5faed ;
  however, it hadn't made it to linus' tree before we published kernels
  for it, so manually recording everything.
