A product performs a series of non-atomic actions to switch between contexts that cross privilege or other security boundaries, but a race condition allows an attacker to modify or misrepresent the product's behavior during the switch.
This is commonly seen in web browser vulnerabilities in which the attacker can perform certain actions while the browser is transitioning from a trusted to an untrusted domain, or vice versa, and the browser performs the actions on one domain using the trust level and resources of the other domain.

Technical Impact: Modify application data; Read application data
Browser updates address bar as soon as user clicks
on a link instead of when the page has loaded, allowing spoofing by
redirecting to another page using onUnload method. ** this is one example of
the role of "hooks" and context switches, and should be captured somehow -
also a race condition of sorts **
