A new speculative vulnerability called ZombieLoad 2, or TSX Asynchronous Abort, has been disclosed today that targets the Transactional Synchronization Extensions (TSX) feature in Intel processors. Using this vulnerability, local attackers or malware can steal sensitive data from the operating system kernel or other processes. Microsoft has released security updates that mitigate these vulnerabilities in Windows Server and Windows Client OS Editions. Intel states that this bug affects a wide range of Intel CPUs, including their Cascade Lake line of processors, which are not affected by other Microarchitectural Data Sampling vulnerabilities.
