This CVE refers to Scenario 1 "Leak frames from the Wi-Fi queue" of CVE-2022-47522.

Affected devices queue frames in order to subsequently change the security context and leak the queued frames. This could allow a physically proximate attacker to intercept (possibly cleartext) target-destined frames.
