  "summary": "net: hip04: fix RX buffer leak on build_skb failure",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: hip04: fix RX buffer leak on build_skb failure\n\nWhen build_skb() fails in hip04_rx_poll(), the driver jumps to the\nrefill path without releasing the current RX buffer and its DMA mapping.\nInstalling a replacement buffer then overwrites the slot references and\nleaks both resources.\n\nKeep the current slot intact and return budget so NAPI retries the same\nbuffer.  Also free a newly allocated RX fragment when dma_map_single()\nfails.\n\nThis issue was found by an in-house static analysis tool.",
