When applying an overlay fails during identifier allocation, the error cleanup routine incorrectly treats negative error codes as valid identifiers. A local user could trigger this vulnerability during resource allocation failures, causing an uninitialized list operation and a null pointer dereference that crashes the kernel, resulting in a Denial of Service (DoS).
