Answer in brief
CVE-2026-64506 records a Unknown severity vulnerability in wifi: rtw89: correct drop logic for malformed AMPDU frames. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
