Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，以下漏洞已得到修复： wifi: mt76: 修复 RRO 3.0 的 RX 数据排队问题 对于 RRO 3.0 版本，从 RRO 数据队列释放的 RX 数据应当被放入指示器队列。这些帧将在指示器队列的 NAPI 上下文中被处理和完成，该上下文仅轮询 MT_RXQ_RRO_IND 列表中排队的 skb；而排入数据队列 ID 的帧会一直滞留在该列表中，直到数据队列的 NAPI 运行，从而导致 RX 数据被阻塞和乱序。

Vulnerability Title
wifi: mt76: fix RX data queuing of RRO 3.0
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: fix RX data queuing of RRO 3.0
For RRO 3.0, RX data released from a RRO data queue should be put to
the indicator queue. The frames are processed and completed in the
context of the indicator queue NAPI, which only polls skbs queued on
the MT_RXQ_RRO_IND list; frames queued under the data queue id are
left sitting on that list until the data queue NAPI happens to run,
stalling and reordering RX data.
