CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's hip04 driver, where a failure in the build_skb() function during packet reception can lead to a resource leak by not releasing the current RX buffer and its DMA mapping. This can result in memory leaks and potential denial of service due to resource exhaustion. Linux system administrators and developers utilizing the affected kernel version should prioritize addressing this issue to maintain system stability and performance.
Original NVD 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.
