CyberRota Analysis
AI-GeneratedThe vulnerability in the Linux kernel affects the RISC-V architecture, specifically related to a node reference leak in the cacheinfo module. This flaw can lead to memory management issues, potentially causing resource exhaustion or instability in the system. Organizations using Linux on RISC-V platforms should prioritize this fix to ensure system reliability and prevent potential exploitation.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: riscv: cacheinfo: Fix node reference leak in populate_cache_leaves Currently, the while loop drops the reference to prev in each iteration. If the loop terminates early due to a break, the final of_node_put(np) correctly drops the reference to the current node. However, if the loop terminates naturally because np == NULL, calling of_node_put(np) is a no-op. This leaves the last valid node stored in prev without its reference dropped, resulting in a node reference leak. Fix this by changing the final `of_node_put(np)` to `of_node_put(prev)`.
