Following the Meltdown and Spectre vulnerabilities at the beginning of this year, Intel recently revealed its new vulnerability, Foreshadow, which is the third major vulnerability in Intel chips this year. The vulnerability is said to affect the Core and Xeon processors released since 2015.
According to reports, an attacker can exploit this vulnerability to bypass the built-in chip security features to obtain sensitive data stored in the “secure blockade” of the processor. The main target is the level 1 cache, which is rated as “high risk.” If to count in the variants of the Meltdown and Spectre vulnerabilities, this is the fifth major vulnerability in x86 processors this year.In addition, the researchers discovered two similar variants called “Foreshadow-NG.” They also attack code, operating systems, hypervisor software, and other microprocessors.
The Meltdown and Spectre vulnerabilities at the beginning of this year have caused many consumers to switch to the AMD platform. The main reason is that after patching the patch, the CPU performance drops significantly. Regarding the Foreshadow vulnerability patch, Intel said that the patch will not have a significant impact on platform performance. In addition, Intel also stressed that the new Xeon and the new Core will be launched before the end of the year, and these new products will be immune to this vulnerability from the bottom of the hardware.
