What are the special instructions that these privileged instructions are actually translated into?
Binary translation is a technique to avoid the CPU virtualization limitation. It works by translating sensitive instructions from the guest operating system into either Hypervisor calls or other undefined CPU opcodes. If the CPU detects a sensitive instruction, it'll be trapped by Hypervisor and handled accordingly. In most cases, many modern CPUs are Non-Virtualizable - meaning they can't handle certain things like context-dependent instructions. This prevents them from being virtualized in order to translate sensitive code ops from Guest OS code using binary translation."
Information security is a huge concern these days because hackers have been linked with many incidents of major data breaches that have been affecting enterprise companies all over the world. Companies that do not maintain up-to-date software patches on their computers are often targeted because these could lead hackers information stored within them also known as confidential information. The more important vulnerabilities get patched first by software developers before lower level vulnerabilities get patched due to varying levels of importance and severity of threat posed for both enterprises and consumers alike
