SmashEx Attack Reaches Most Secure Areas of Intel CPUs to Steal Data
Academics from universities developed a new attack technique, dubbed SmashEx, that runs into Intel SGX and can allow adversaries to steal confidential data from Intel CPUs. The new vulnerability tracked by Intel as CVE-2021-0186 allows attackers to inject an asynchronous exception during the code execution. Experts suggest implementing atomicity at the OS-enclave interface to reduce the risk of such attacks.
