In the Linux kernel, the following vulnerability has been resolved: mt76:
fix potential DMA mapping leak With buf uninitialized in
mt76_dma_tx_queue_skb_raw, its field skip_unmap could potentially inherit a
non-zero value from stack garbage. If this happens, it will cause DMA
mappings for MCU command frames to not be unmapped after completion
