Details

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
