AI-suggested

A fix has been implemented in the Linux kernel to correct the packet accounting logic in the mt76 driver. Users should apply the official kernel updates containing this fix once available. No other mitigation actions are indicated.

Description

A vulnerability in the Linux kernel's mt76 WiFi driver caused incorrect accounting of non-AQL packets for Multi-Link Operation (MLO) stations. This flaw could lead to the transmission scheduler permanently refusing to service a station due to inflated packet counters. The issue was fixed by correcting the packet accounting logic to use the actual wireless client identifier (wcid) used for transmission.
