"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nriscv: cacheinfo: Fix node reference leak in populate_cache_leaves\n\nCurrently, the while loop drops the reference to prev in each iteration.\nIf the loop terminates early due to a break, the final of_node_put(np)\ncorrectly drops the reference to the current node.\n\nHowever, if the loop terminates naturally because np == NULL, calling\nof_node_put(np) is a no-op. This leaves the last valid node stored in\nprev without its reference dropped, resulting in a node reference leak.\n\nFix this by changing the final `of_node_put(np)` to `of_node_put(prev)`."
