In the Linux kernel, the following vulnerability has been resolved:
net: altera-tse: fix skb leak on DMA mapping error in tse_start_xmit()
When dma_map_single() fails in tse_start_xmit(), the function returns
NETDEV_TX_OK without freeing the skb. Since NETDEV_TX_OK tells the
stack the packet was consumed, the skb is never freed, leaking memory
on every DMA mapping failure.
Add dev_kfree_skb_any() before returning to properly free the skb.
