Note

A covert channel can be thought of as an emergent resource, meaning that it was not an originally intended resource, however it exists due the application's behaviors.
As of CWE 4.9, members of the CWE Hardware SIG are working to improve CWE's coverage of transient execution weaknesses, which include issues related to Spectre, Meltdown, and other attacks that create or exploit covert channels. As a result of that work, this entry might change in CWE 4.10.
