On Wednesday, OpenBSD founder Theo de Raadt posted a rant in a mailing list that alleged Intel's Core 2 processors were plagued with many "serious bugs." De Raadt didn't mince words:
These processors are buggy as hell, and some of these bugs don't just cause development/debugging problems, but will *ASSUREDLY* be exploitable from userland code.De Raadt links a list of errata (PDF) from Intel's site and explains, "Hiding in this list are 20-30 bugs that cannot be worked around by operating systems, and will be potentially exploitable. I would bet a lot of money that at least 2-3 of them are."
As is typical, BIOS vendors will be very late providing workarounds / fixes for these processors bugs. Some bugs are unfixable and cannot be worked around. Intel only provides detailed fixes to BIOS vendors and large operating system groups. Open Source operating systems are largely left in the cold.
The guys at ExtremeTech have asked Intel to comment, but the company would not confirm or deny Raadt's assessment or discuss any plans for a respin or recall of Core 2 chips. Intel spokesman Nick Knupffer appeared to downplay the allegations. "All processors from all companies have errata, and Intel has a well-known errata communication process to inform our customers and the public," he stated, adding that Intel investigates all errata and issues fixes if problems and vulnerabilities are found.
