This vulnerability allows unprivileged attackers, even those with limited access, to read and write any part of the computer's memory and to control peripheral devices like network cards. GhostWrite renders the CPU's security features ineffective and cannot be fixed without disabling around half of the CPU's functionality.
The attack is 100% reliable, deterministic, and takes only microseconds to execute. Even security measures like Docker containerization or sandboxing cannot stop this attack. Additionally, the attacker can hijack hardware devices that use memory-mapped input/output (MMIO), allowing them to send any commands to these devices.
