AMD's random number generator can't generate a 0?

AMD's random number generator, specifically the RDSEED instruction in their Ryzen and EPYC processors, has a flaw. This instruction is designed to generate truly random numbers for use in security applications. However, it appears that the instruction can't generate a 0, which is a major limitation. This is due to the way the instruction works, using thermal noise from the CPU's digital circuitry to generate randomness. The lack of a 0 output can be a problem for certain applications, such as cryptographic systems, which require a wide range of possible inputs.
