Intel CPUs Vulnerable to New ‘SGAxe’ and ‘CrossTalk’ Side-Channel Assaults

Cybersecurity researchers have found two distinct attacks that may be exploited against modern Intel processors to leak delicate information from the CPU’s reliable execution environments (TEE). Known as SGAxe, the first of the defects is an evolution of the formerly uncovered CacheOut attack (CVE-2020-0549) earlier this year that allows an opponent to retrieve the material from the CPU’s
