I have tried to find out just what the bug was. Since I've been retired a few years I have fewer contacts who might actually know. The most informed guess I have heard is that the Intel hyper-threading can leave data in the cache that AMD processes do not. This can allow a cache update to drop a change in the part of the address page table which is generally used by the kernel, thereby changing a permission. If so, then the AMD processors really wouldn't exhibit the same vulnerability.
