Intel processors released in the past 5 years contain an unpatchable vulnerability that could allow hackers to compromise almost every hardware-enabled security technology. The vulnerability resides in the hard-coded firmware running on the ROM (“read-only memory”) of the Intel’s Converged Security and Management Engine (CSME), which can’t be patched without replacing the silicon. Only the latest Intel 10th generation processors, Ice Point chipsets and SoCs, are not vulnerable to this issue. The issue can also be exploited to recover the Chipset Key, a root cryptographic key or sort of a master password.
