Details

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.
