A vulnerability in the Linux kernel's SUNRPC subsystem related to the handling of backchannel requests during NFS callback service teardown has been resolved. The issue involves a race condition where backchannel receive operations can complete requests while the callback service is being destroyed, potentially leading to resource leaks and use-after-free conditions. The fix involves properly closing the producer side before stopping callback threads and ensuring requests are correctly freed and drained before service destruction.
