Restrict network access to the kadmind service to trusted hosts only. Alternatively, disable kadmind and use the kadmin.local server-side command line tool for administrative tasks if feasible.

Description

CVE-2026-112319 is a vulnerability in the GSS-RPC layer of MIT Kerberos 5 used in Red Hat Enterprise Linux 10. It allows remote authenticated users to cause a denial of service by triggering unbounded memory allocations during XDR decoding of crafted RPC requests. This leads to memory exhaustion or excessive CPU consumption in the Kerberos administration daemon (kadmind). Exploitation requires valid Kerberos authentication and affects process availability without compromising data confidentiality or integrity.
