CVE-2026-16277 · Rpcbind: rpcbind: stack buffer overflow in rpcinfo rpcbaddrlist()
This page contains facts from public vulnerability sources. Check the original advisory before updating.
A stack-based buffer overflow was found in rpcbind's rpcinfo utility. When querying a remote rpcbind service with `rpcinfo -l`, address information returned by the server is copied into a fixed-size buffer without sufficient bounds checking. A malicious or compromised rpcbind server could use this flaw to crash the rpcinfo client, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
