It allows an unauthorized process to read data from any address that is mapped to the current process’s memory space, because instruction pipelining in the affected processors means that the data from the unauthorized address will almost always be temporarily loaded into the CPU’s cache during speculative execution, from which it can be recovered using other techniques, even if the original read instruction eventually fails due to privilege checking and never produces a readable result. It allows a rogue process to read any physical, kernel or other process’s mapped memory, regardless of whether or not it should be able to do so.

Meltdown is a hardware vulnerability affecting Intel x86 microprocessors and some ARM-based microprocessors.

Today we are going to disccuss how to “Check Metltadown vulnerability in any CPU” by using a script. Hello Friends!! You must be heard of the latest vulnerbility “Meltdown” which has been discovered almost in every CPU having intel processessor, from this link you can check list of vulnerable CPU discription.
