Research Paper: RISCVuzz: Discovering Architectural CPU Vulnerabilities via Differential Hardware Fuzzing
minus-squareAlphane MoonOPMlinkEnglish2•edit-21 month agoThis seems like a pretty major bug. From my understanding, any code can run with full privileges when running on this CPU. Some interesting discussion points at the end of the article about how RISC-V as an ISA could make it more difficult to mitigate such flaws.
