  "details": "Trying to read malformed HAMT sharded directories can cause panics and virtual memory leaks. If you are reading untrusted user input, an attacker can then trigger a panic.\n\nThis is caused by bogus `fanout` parameter in the HAMT directory nodes. A workaround is to not feed untrusted user data to the decoding functions.",
