Дата: 15.01.2020. Автор: CISOCLUB. Категории: Подкасты и видео по информационной безопасности

There exists a «feature» in the x86 architecture that, due to improper programming by many operating system vendors, can be exploited to achieve local privilege escalation.

This issue, very likely, impacts other operating systems on the x86 architecture.
