What is meltdown meaning?

Meltdown refers to a major security vulnerability that affects almost all modern microprocessors, including those in computers, smartphones, and other electronic devices. It allows malicious actors to gain unauthorized access to sensitive information like passwords, encryption keys, and personal data stored within the computer’s memory. The vulnerability is caused by a hardware design flaw in the processor that allows unauthorized access to privileged information. The discovery of Meltdown in 2018 led to extensive efforts to patch computer systems by manufacturers and software providers.
