CVE-2026-16277

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.
