expose memory contents previously stored in microarchitectural buffers to a
malicious process that is executing on the same CPU core. A local attacker
could use this to expose sensitive information. (CVE-2019-11135)

restrict access to a voltage modulation interface. A local privileged
attacker could use this to cause a denial of service (system crash).
