Intel CPUs Vulnerable to New 'SGAxe' and 'CrossTalk' Side-Channel Attacks

Cybersecurity researchers have discovered two distinct attacks that could be exploited against modern Intel processors to leak sensitive information from the CPU’s trusted execution environments (TEE).

Called SGAxe, the first of the flaws is an evolution of the previously uncovered CacheOut attack (CVE-2020-0549) earlier this year that allows an attacker to retrieve the contents from the CPU’s
