Spectre (security vulnerability)
Mitigation
Since Spectre represents a whole class of attacks, most likely, there cannot be a single patch for it. While work is already being done to address special cases of the vulnerability, the original website devoted to Spectre and Meltdown states: "As [Spectre] is not easy to fix, it will haunt us for a long time." At the same time, according to Dell: "No 'real-world' exploits of these vulnerabilities [i.e., Meltdown and Spectre] have been reported to date [February 7, 2018], though researchers have produced proof-of-concepts." Several procedures to help protect home computers and related devices from the vulnerability have been published.
