Frightening open on processors with Zen 3 architecture

Amd, which has taken the lead in processor competition with the Ryzen series, has become a target for hackers. The company acknowledged that an Intel Spectre-like vulnerability has been discovered in processors with Zen 3 architecture.

AMD Zen 3 architecture is on the agenda with the vulnerability

The company recently released a report called AMD Predictive Store Forwarding Security Analysis. Comparing the vulnerability discovered in the published report to Spectre v1, v2, and v4, AMD noted that similar attack scenarios apply to Zen 3 architecture processors.

Predictive Store Forwarding (PSF), developed to allow the processor to react quickly, predicts the next instruction to be performed by the processor.

Incorrect prediction of PSF technology is a vulnerability. This allows hackers to access users’ data.

Explaining that the wrong prediction process occurs in 2 ways, the company underlined that hackers can trigger the wrong prediction process with malicious code.
