CVE-2026-68135
Detail
Received This CVE record has recently been published to the CVE List and has been included within the NVD dataset.
Description
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.
