Details

Peter Pi discovered a buffer overflow in the virtio network backend
(vhost_net) implementation in the Linux kernel. An attacker in a guest may
be able to use this to cause a denial of service (host OS crash) or
possibly execute arbitrary code in the host OS. (CVE-2019-14835)

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. (CVE-2019-15030)

It was discovered that the Linux kernel on PowerPC architectures did not
properly handle exceptions on interrupts in some situations. A local
attacker could use this to expose sensitive information. (CVE-2019-15031)
