In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: correct drop logic for malformed AMPDU frames
The previous commit aims to fix issue caused by malformed AMPDU frames. But the drop logic fails to deal with the first AMPDU packet paired with certain range of sequence number, and leads to unexpected packet drop. It is more likely to encounter this failure when there are busy traffic during rekey process and could lead to disconnection from the AP. Fix this by adding a initial state judgement and only reset status during pairwise rekey.

A flaw was found in the Realtek 802.11ac wireless driver (rtw89) within the Linux kernel. A remote attacker, within adjacent network range, could send specially crafted malformed Aggregated MAC Protocol Data Unit (AMPDU) frames. This incorrect handling of frames, particularly during rekey processes, leads to unexpected packet drops. The consequence is a denial of service (DoS), causing affected clients to disconnect from the wireless access point.
