Generally the memory used by processor is very secure and only kernel in operating system (main program that executes all the instructions) can access or modify this memory. No user program or software can access the memory directly. So the data remains secure while the CPU is processing it. This secure data can be saved passwords, encryption keys and critical documents. The devices that use processors can be affected by this kind of attacks! This means every smart device connected to any kind of network! Meltdown and Spectre work on computers, Mobiles and Cloud.
