Meltdown is a significant software vulnerability that was discovered in 2018, alongside another threat known as Spectre. These vulnerabilities affected virtually every modern microprocessor and sparked widespread concern due to their potential to expose confidential user data to hackers. Both Meltdown and Spectre exploit the hardware optimization function called "speculative execution," allowing attackers to extract sensitive information from cache memory. Despite being made aware of these threats, Intel and other microprocessor designers have struggled to fully mitigate them, leading to continued concerns and incidents related to these vulnerabilities. In one notable instance, Singtel, the parent company of Optus, experienced a 16-hour-long network outage in November, affecting approximately 10 million customers. The outage was attributed in part to Meltdown, with Singtel distancing itself from its subsidiary’s claim that a routine upgrade at the parent company contributed to the network meltdown. This incident led to significant fallout, including the stepping down of Singtel's CEO, Kelly Bayer Rosmarin. In response to these ongoing threats, MITRE rolled out four new common weakness enumerators (CWEs) in February 2024 to help microprocessor designers better secure processors against vulnerabilities such as Spectre and Meltdown. One of these, CWE-1420, specifically addresses the exposure of sensitive information during transient or speculative execution, the function associated with Meltdown and Spectre. Despite these efforts, the process of fully securing microprocessors against these vulnerabilities remains an ongoing challenge.
