and I had to actually read that thread carefully to understand that in the places where they refer to 32-bit being susceptible, they are referring to Meltdown, not Spectre. The way it was worded it really wasn't obvious, but this makes it clear: > Many of us are concerned that we are running 32-bit systems that are > still vulnerable to meltdown; Now, back to our AMD64 processors... Is it possible to access/exploit 64bit-specific instructions and features, through a 32-bit OS? That is the question. We need to find out if some of these features that Spectre relies upon, are still active/available when running in 32bit compatibility mode for a 32bit OS with 32bit software. |
