This CVE refers to Scenario 3 "Override client’s security context" of CVE-2022-47522. Affected devices can be tricked into associating a newly negotiated, attacker-controlled, security context with frames belonging to a victim. This could allow a physically proximate attacker to decrypt frames meant for the victim.
