Spectre flaws hit commercial RISC-V chips
3 min read
Researchers found commercial out-of-order RISC-V processors, including SiFive P550 and T-Head Xuantie C910/C920, are vulnerable to all major Spectre variants. A proof-of-concept exploit leaked Linux kernel memory on the C910 at 338 B/s. In-order RISC-V chips like SiFive U74 appear unaffected.
