Key Information Vulnerability Type: Use-after-free caused by cyclic delayed work Affected Module: net: mscc: ocelot Issue Description: - The original code calls in to cancel the cyclic delayed work item . - If the work item is already running, may fail. - waits for all pending work items to complete before destroying the workqueue, but it cannot prevent the delayed work item from being rescheduled within the function. - This leads to the delayed work item being queued again after the timer expires, triggering a warning.
