Description OSIDB Bzimport 2026-08-28 07:43:38 UTC 
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().
