HighCVSS 7.5/10Last modified Nov 13, 2026

Description

The AUTH_GSSAPI handler in lib/rpc/svc_auth_gssapi.c in MIT Kerberos 5 (aka krb5) does not free decoded arguments on certain error paths, which allows remote attackers to cause a denial of service (memory exhaustion in kadmind) via crafted AUTH_GSSAPI_INIT requests that trigger authentication failures.
