An attacker in a guest may be able to use this to cause a denial of service or possibly execute arbitrary code in the host OS. It was discovered that the Linux kernel on PowerPC architectures did not properly handle Facility Unavailable exceptions in some situations. A local attacker could use this to expose sensitive information. Various other issues were also addressed.
