The vulnerability of microprogramming software for Intel and AMD processors allows attackers to extract sensitive information from the kernel’s memory or launch attacks on host systems from virtual machines.

The vulnerability of microprogramming software for Intel and AMD processors lies in errors during the processing of the “ret” instruction, which retrieves an address for transitioning from the stack. Exploiting this vulnerability can allow attackers to extract protected information from the...
