# MIT Kerberos: kadmind memory leak lets authenticated users exhaust memory

Link for people: https://infrastack.ai/live/CVE-2026-112316 (this .md is for agents)

A failed decode in the kadmind admin RPC code of MIT Kerberos 5 does not free partially decoded data. A remote user with valid credentials can send crafted RPC requests to leak memory in kadmind and cause a denial of service.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

xdr_krb5_tl_data() in lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) does not free partially decoded data on failure, which allows remote authenticated users to cause a denial of service (memory leak in kadmind) via crafted RPC requests that trigger a decode failure.
