guru3d CPU bug affects Intel CPUs; 10th, 11th, and 12th generations

The researchers that discovered this attack method were engaged in the discovery of multiple side-channel techniques that impact various CPUs, including the well-known Meltdown and Spectre attacks and their variations. However, unlike Meltdown and Spectre, which are transitory execution threats, AEPIC Leak arises owing to an architectural fault that results in the leaking of sensitive data without the need of a side channel. They called it "the first CPU bug capable of structurally revealing critical info."

 

Users whose PCs are powered by a recent Intel CPU are likely vulnerable by the vulnerability. At the same time, those who do not utilize SGX are not at risk, according to the researchers. The vulnerability can be avoided by disabling APIC MMIO or avoiding SGX.

Another day, another new vulnerability.

The new trick to reducing performance of older product

We will only allow the OS on newer hardware because it is the only secure hardware.... Errr,we'll get back to you later..... (Microsoft representative on the cpu requirements for Windows 11)

Been complaining about this since 8.  Seems its still a thing.  Are they going to start blocking older CPU's again instead of just decreasing performance?  It's always about the same thing, buying the latest and greatest, which I'm okay with to a point (looks at my 5800x / 6900xt).  It just really grinds my gears when they "patch" older equipment to be slower on purpose, or flat out block the use of older equipment entirely.
