Vulnerability Details CVE-2021-47064
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
