NVD · officialPublished Nov 9, 2026Risk 23/100

clnttcp_call() in lib/rpc/clnt_tcp.c in MIT Kerberos 5 (aka krb5) does not free the RPC reply verifier between retries, which allows remote attackers to cause a denial of service (memory leak in GSS-RPC client programs) by injecting RPC replies with mismatched XIDs or by triggering authentication retries.
