hw: cpu: speculative execution permission faults handling

An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions a commonly used performance optimization. There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant...

Fixing the Meltdown and Spectre vulnerabilities

Two days ago, Graz University of Technology published a paper describing a pair of attacks on common microprocessors. The underlying vulnerability affects Intel, AMD, and ARM processors. All contemporary microprocessors pre-execute instructions. In other words, the vulnerability bypasses address...

Spectre and Meltdown Attacks

After a week or so of rumors, everyone is now reporting about the Spectre and Meltdown attacks against pretty much every modern processor out there. These are side-channel attacks where one process can spy on other processes. They affect computers where an untrusted browser window can execute cod...
