- Summary
- net: hip04: fix RX buffer leak on build_skb failure
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
net: hip04: fix RX buffer leak on build_skb failure
When buildskb() fails in hip04rx_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 dmamapsingle() fails.
This issue was found by an in-house static analysis tool.
