Researchers at Vrije University in Amsterdam revealed on Wednesday that Intel's server-grade processors suffer from a vulnerability, which they dubbed NetCAT. The vulnerability enables a side-channel attack that can infer what a CPU is working on and is said to rely on issues with two Intel technologies found primarily in the Xeon CPU line: Data-Direct I/O Technology (DDIO) and Remote Direct Memory Access (RDMA). According to the researchers, AMD chips aren't impacted by the bug.
