Description Thomas Deutschmann gentoo-dev 2020-11-13 00:11:52 UTC
A flaw was found in the Linux kernel's implementation of Intel's Running Average Power Limit (RAPL) implementation. A local attacker could infer secrets by measuring power usage and also infer private data by observing the power usage of calculations performed on the data.
