by MITRE • 08/28/2026

In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7996: Fix NULL pointer dereference in mt7996_init_tx_queues()

When MT76_NPU and CONFIG_NET_MEDIATEK_SOC_WED are enabled and mt76 detects properly the Airoha NPU SoC, mt7996_init_tx_queues() will dereference a NULL WED pointer. Fix the issue by always passing the WED pointer from mt7996_dma_init().
