A microarchitectural timing flaw was found on some Intel processors. A corner case exists where data in-flight during the eviction process can end up in the “fill buffers” and not properly cleared by the MDS mitigations. The fill buffer contents (which were expected to be blank) can be inferred using MDS or TAA style attack methods to allow a local attacker to infer fill buffer values.
