CVE ID	CVE-2020-8752
Versions	Prior to 11.8.80, 11.12.80, 11.22.80, 12.0.70, 14.0.45
CVSS Score	9.4
Description	Out-of-bounds write in the IPv6 subsystem of Intel AMT and ISM that enables remote unauthenticated to escalate privileges. Successful exploitation requires vulnerable products to be configured with IPv6 which is not a default configuration according to Intel.

CVE ID	CVE-2020-12321
Versions	Before 21.110
CVSS Score	9.6
Description	Improper buffer restriction in Wireless Bluetooth products that enables unauthenticated escalation of privilege via adjacent access (Local Area Network only).

Below are additional details for some of the issues addressed.

Patch Against PLATYPUS Side-Channel Attacks:

Named Platypus, an acronym for “Power Leakage Attacks: Targeting Your Protected User Secrets,” the attack targets the RAPL interface of Intel processors.

RAPL, which stands for Running Average Power Limit, is a component that allows firmware or software applications to monitor power consumption in the CPU and DRAM.

Above all, Two new vulnerabilities CVE-2020-8694 and CVE-2020-8695 dubbed PLATYPUS and disclosed by researchers.

Importantly, Potential security vulnerabilities in the Intel® Running Average Power Limit (RAPL) Interface may allow information disclosure.

Description: Successful exploitation of the two vulnerabilities could lead to information leakage from the Running Average Power Limit (RAPL) Interface, used to monitor and manage CPUs and DRAM memory power consumption.

Additional technical info is available in this academic research paper [PDF], in Intel’s PLATYPUS security advisory, as well as in Xen’s security advisory.
