Therefore, refcount related to the search iterators should be cleaned\nup after the search is complete.\n\nUse the __free() cleanup macro to ensure the refcount is decremented when the\ntemporary pointer goes out of scope.\n\nAdditionally, increment the refcount when caching a root pointer. This ensures\nthe in-use refcount is separate from the temporary search refcounting.\n\nFinally, drop the redundant \"root = NULL\" before the second search loop. The\npci_get_class() iterator always decrements the refcount of its \"from\"\nargument, so the first loop can only fall through with \"root\" already NULL.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/27600805e62f800bacf990354632eae4e487d34c","tags":[]},{"url":"https://git.kernel.org/stable/c/84e3a71d11d8593c127b468d75b2653af5074f81","tags":[]},{"url":"https://git.kernel.org/stable/c/aa2a4277ad42fd8f918c6dc652473946a253f7b0","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
