A use-after-free vulnerability in the Linux kernel's NFS server (nfsd) was resolved by protecting the cl_cb_session pointer with RCU mechanisms. The flaw allowed a session to be freed while an inflight callback still referenced it, potentially causing memory corruption. The fix involves converting cl_cb_session to an RCU-protected pointer, deferring freeing until after an RCU grace period, and ensuring proper synchronization between session teardown and callback processing.
