commit 77dbd7a95e4a4f15264c333a9e9ab97ee27dc2aa upstream. crypto_larval_lookup should only return a larval if it created one. Any larval created by another entity must be processed through crypto_larval_wait before being returned. Otherwise this will lead to a larval being killed twice, which will most likely lead to a crash.
