Intel Faced Expanded Spectre-Class CPU Flaws as Mitigations Shifted to Hardware

Researchers and industry reporting revealed that Intel processors were affected by a broader set of speculative-execution vulnerabilities beyond the original Meltdown and Spectre disclosures, including eight additional issues dubbed Spectre-NG. Several of the newly reported flaws were described as high risk, with at least one capable of crossing virtual machine boundaries and threatening cloud environments by exposing sensitive data such as passwords and cryptographic keys; reports also said Intel SGX protections were not sufficient against some of these attacks. The wider Spectre/Meltdown family affected Intel most heavily for Meltdown and Intel, AMD, and Arm for Spectre, reinforcing warnings that complete remediation would ultimately require hardware changes rather than software alone.
