CVE-2026-68135

In the Linux kernel, the following vulnerability has been resolved:

net: hip04: fix RX buffer leak on build_skb failure

When build_skb() fails in hip04_rx_poll(), the driver jumps to the

refill path without releasing the current RX buffer and its DMA mapping.

Installing a replacement buffer then overwrites the slot references and

leaks both resources.

Keep the current slot intact and return budget so NAPI retries the same

buffer. Also free a newly allocated RX fragment when dma_map_single()

fails.

This issue was found by an in-house static analysis tool.
