Intel Processors Affected by New “Crosstalk” Vulnerability

Intel has released a list of processors that are affected by a new vulnerability called special register buffer data sampling (SRBDS). Otherwise known as “crosstalk,” this is an execution attack that, as the company explains, “may allow data values from special registers to be inferred by malicious code executing on any core of the CPU.”



“On some processors, the data returned for a special register read is staged in a shared microarchitectural buffer and then transferred to the microarchitectural fill buffer within the physical core that performed the read,” elaborated Intel.



“That core can then use the value from the microarchitectural fill buffer (for example, the core could copy the value into software-visible registers). This...

Jeez. It never ends...

I'd feel sorry for intel if I wasn't having to constantly run 100's of bios updates and patch applications every other month because they are not security minded and have had the same researchable architecture for the last 2 decades.

Maybe I'm being harsh but the best change for security is a new product stack designed to work in a new way with a balance in security and performance. If you can do that then your primary vulnerabilities will be in home user systems that are ran for too long on too old of an OS without product updates and security updates applied.

The enterprise would be on point buying and upgrading just 1 foot out of step.

At this point I wouldn't be surprised if its discovered Intel cpus are affected by the corona virus.

I seriously laughed out loud at this.

I’m thinking I made the right move when I switched out to AMD. These vulns (realistic or not) just keep growing.

In business, I'd be concerned. For home systems, not so much.

Yeah my work machine comes home with me daily and along with me for travels. I have had it shut off and only on when needed. Intel Laptop CPU, Im not paranoid but Im not trying to be the weak point in the company either. Next laptop will have AMD in it unless Intel fixes this all next CPU arch.

I agree. I don't feel any less secure using Intel for my home machines.
