Exploiting System Management Mode via Extended Instruction Execution Delay

#hardware #vulnerability #security #exploit #x86

The article demonstrates a method to exploit System Management Mode (SMM) on x86 CPUs by using an extended instruction execution delay to disrupt synchronization, enabling potential attacks. It highlights a critical vulnerability in firmware's handling of SMM coordination between CPU cores.
