  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: altera-tse: fix skb leak on DMA mapping error in tse_start_xmit()\n\nWhen dma_map_single() fails in tse_start_xmit(), the function returns\nNETDEV_TX_OK without freeing the skb. Since NETDEV_TX_OK tells the\nstack the packet was consumed, the skb is never freed, leaking memory\non every DMA mapping failure.\n\nAdd dev_kfree_skb_any() before returning to properly free the skb.",
