  It's astonishing how few technical details are provided in this article (like the nature of the vulnerability, whether it affects RISC-V's design in general or only a specific implementation, and whether it is readily fixable).

  I tried to find more details and found that slashdot user st0nerhat had found a more technical summary in Chinese, which you can see translated here:

  This is a bug in a student-built microarchitecture, not an issue with the ISA.

  Not a great article, as it attacks RISC-V for no good reason.

  The article has little useful data - this looks like it's the original paper:
