Descriptions

A potential power side-channel vulnerability in
AMD processors may allow an authenticated attacker to monitor the CPU power
consumption as the data in a cache line changes over time potentially resulting
in a leak of sensitive information.

Una posible vulnerabilidad de canal lateral de energía en los procesadores AMD puede permitir a un atacante autenticado controlar el consumo de energía de la CPU a medida que los datos de una línea de caché cambian con el tiempo, lo que podría dar lugar a una fuga de información confidencial.
