The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to a resource leak in the hip04_rx_poll() receive path when handling a build_skb() failure. A local user can trigger build_skb() failures to cause a denial of service.
The issue leaks an RX buffer and its DMA mapping when slot references are overwritten, and also involves a newly allocated RX fragment if dma_map_single() fails.
