What to do
AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel. Users should apply the official kernel updates that include the corrected drop logic for malformed AMPDU frames in the rtw89 driver. No additional mitigation steps are indicated.
Description
A vulnerability in the Linux kernel's wifi driver rtw89 involves incorrect drop logic for malformed AMPDU frames. This flaw causes unexpected packet drops, particularly affecting the first AMPDU packet with certain sequence numbers during busy traffic and rekey processes. The issue can lead to disconnection from the access point. The fix involves adding an initial state check and resetting status only during pairwise rekey.
