A flaw was addressed in the Linux kernel’s SUNRPC implementation affecting deferred RPC request handling. When an RPC request is deferred, the internal rq_xprt_ctxt pointer is moved from the active service request to a deferred request structure. Under certain rare conditions where a request is deferred multiple times, the old context pointer is not cleared before reuse. This can lead to the context being freed twice while still referenced, causing memory corruption and likely resulting in a kernel oops/crash
