Score breakdown

Insufficient access control in the Linux kernel driver for some Intel(R) Processors may allow an authenticated 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) driver in the Linux kernel did not properly restrict access to power data. A local attacker could possibly use this to expose sensitive information.
