AMD's 'Inception' vulnerability patch made a mistake, and CPU performance dropped by up to 54% after installation

News from this website on August 17th. AMD recently disclosed a newly discovered "Inception" CPU vulnerability. This website reported earlier that this vulnerability can leak sensitive data. AMD has recently released corresponding patches to solve the vulnerability problem. However, foreign media Phoronix recently tested the new patch and found that the CPU performance of the device after installing the patch dropped significantly. It is reported that all Zen CPUs are affected by the Inception vulnerability. Hackers can create an instruction to guide the CPU into a repeated function, thereby overflowing the CPU and causing data leakage. AMD has urgently released a repair patch for the "Family 19" processor (ie EPYC processor). However, foreign media Phoronix found after a recent test that after installing the repair patch, "intensive computing" applications (such as MariaDB software), there was a significant performance drop, with a performance loss of more than 50%, indicating that the patch "seriously affects software based on data processing"
