The Linux kernel's rtw89 WiFi driver contained a flaw in handling malformed AMPDU frames. The previous fix for malformed AMPDU frames did not correctly handle the first AMPDU packet paired with specific sequence numbers, resulting in unintended packet drops. This failure was more likely under heavy traffic during rekeying and could cause disconnection from the access point. The fix introduced an initial state judgment and limited status resets to pairwise rekey operations, correcting the drop logic.

This vulnerability could cause unexpected packet drops in the WiFi driver, leading to potential disconnections from the access point during network rekeying under busy traffic conditions. There is no indication of remote code execution or privilege escalation. The impact is primarily a denial of service in the form of network disconnection.

A fix for this vulnerability has been implemented in the Linux kernel by correcting the drop logic in the rtw89 driver. Users should apply the official Linux kernel updates that include this correction. Patch status is not explicitly confirmed in the provided data; therefore, check the vendor or Linux kernel advisory for the current remediation guidance.
