A fix is available that corrects the pointer handling in the mt7996 wireless driver. Users should apply the updated Linux kernel versions that include this patch. Specific affected versions are listed and should be upgraded or patched accordingly.
Description
A NULL pointer dereference vulnerability in the Linux kernel's mt7996 wireless driver was fixed. The issue occurs in the mt7996_init_tx_queues() function when MT76_NPU and CONFIG_NET_MEDIATEK_SOC_WED are enabled, and the Airoha NPU SoC is detected. This leads to dereferencing a NULL WED pointer. The fix ensures the WED pointer is always passed correctly from mt7996_dma_init().
