Hi, recently i read a news about Total Meltdown on Bleeping Computer news, and i read that the flaw only can be exploited by physical access.
"The flaw is not remotely exploitable, and attackers need either physical access to a PC, or they need to infect the PC with malware beforehand."
if i remember correctly when Meltdown found, many article said that Meltdown can be exploited through local access.
what i want to know what the difference between local and physical access ? why Meltdown and Total Meltdown different on their access to exploit? is it because Microsoft already patch some things that make Meltdown need local access to exploit to? so it changes to physical?
