  machine) subsystem's handling of the XSAVE CPU feature. On hosts without the
  XSAVE CPU feature, using qemu userspace, an unprivileged local attacker could
  exploit this flaw to crash the system. (CVE-2012-4461)

  A flaw was discovered in the Linux kernel's handling of script execution
  when module loading is enabled. A local attacker could exploit this flaw to
  cause a leak of kernel stack contents. (CVE-2012-4530)
  
  Florian Weimer discovered that hypervkvpd, which is distributed in the
  Linux kernel, was not correctly validating source addresses of netlink
  packets. An untrusted local user can cause a denial of service by causing
  hypervkvpd to exit. (CVE-2012-5532)";
