ETH Zurich researchers discover new security vulnerability in Intel processors
ethz.ch
Computer scientists at ETH Zurich discover new class of vulnerabilities in Intel processors, allowing them to break down barriers between different users of a processor using carefully crafted instruction sequences. Entire processor memory can be read by employing quick, repeated attacks.
  • The new class of vulnerabilities in Intel processors arises from speculative technologies that anticipate individual computing steps.
  • Openings enable gradual reading of entire privilege memory contents of shared processor (CPU).
  • All Intel processors from the last 6 years are affected, from PCs to servers in data centres.

    Honestly, it does sound a bit like a hardware defect somewhere. Usually everything should work OOTB unless you are doing something really specific.

    If you haven’t already done so, try updating the BIOS.

    You mentioned the RAM being fine - have you run Memtest86+ for several hours? One pass is usually not enough to rule out memory malfunctions.

    If you have a spare drive, try installing Linux Mint on it. If it still crashes, you can rule out Windows (and if it doesn’t, you could install a clean Windows on that same drive and try again).

    You could also purchase a cheap AM4 motherboard (they start at like 60 bucks) to check if the issues still occur and refund it within the return window.

      Hey, thanks for the reply. Yeah I ran memtest at some point, but I’ve also used the memory in a different machine and had no trouble with it.

      I’ve done several bios updates hoping for some fix, but no beans.

      It does feel like a hardware defect, but the unfortunate bit is that the machine ran great for over a year, then suddenly started giving me trouble at some point, so I’m probably outside of any warranty period. That’s basically the only reason I haven’t RMA’d it already.

      Installing mint is a pretty good idea, I could try that. But yeah, a new AM4 mobo is probably my best bet, I can’t tell you how frustrating it is though…

      Thanks for the ideas, I appreciate it!
