What is the difference between meltdown and Spectre?
Can Spectre and meltdown be exploited remotely?
Spectre and the related Meltdown CPU vulnerabilities were first publicly disclosed on Jan. 3. “Spectre attacks require some form of local code execution on the target system,” the Graz University researchers wrote.
Is coffee lake affected by Meltdown and Spectre?
New Intel Coffee Lake CPUs offer hardware-based protections against some -but not all- Spectre and Meltdown variants. Intel’s new ninth-generation CPUs come packed with hardware-based protections against two variants of the infamous Meltdown and Spectre speculative execution attacks.
Should I disable Spectre patch?

Which systems are affected by Meltdown? Desktop, Laptop, and Cloud computers may be affected by Meltdown.
What are the Spectre vulnerabilities in Windows 10?
Microsoft includes these Spectre vulnerabilities in one advisory. They prey on systems with microprocessors that use speculative execution and branch prediction, and they might allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.
