CVE-2020-8695
Published: 10 November 2020
Observable discrepancy in the RAPL interface for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access.
From the Ubuntu security team
Moritz Lipp, Michael Schwarz, Andreas Kogler, David Oswald, Catherine Easdon, Claudio Canella, and Daniel Gruss discovered that the Intel Running Average Power Limit (RAPL) feature of some Intel processors allowed a side-channel attack based on power consumption measurements. A local attacker could possibly use this to expose sensitive information.
