kernel: SUNRPC: double free xprt_ctxt while still in use

A flaw was addressed in the Linux kernel’s SUNRPC implementation affecting deferred RPC request handling. When an RPC request is deferred, the internal rqxprtctxt pointer is moved from the active service request to a deferred request structure. Under certain rare conditions where a request is...

kernel: SUNRPC: lock against ->sock changing during sysfs read

A vulnerability was found in the Linux kernel's SUNRPC component, where a race condition exists during sysfs read operations due to improper handling of the -sock pointer. If the mutex -recvmutex is not held, -sock may change asynchronously, leading to a potential kernel oops. This vulnerability...
