Sep 23 PATCH SHIPPED — CVE-2026-73198 (Red Hat Enterprise Linux 9). Fixed in Red Hat Enterprise Linux 9 0:4.13.4-1.el9_8.
Description
A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit a vulnerability in the `/ipa/i18n_messages` endpoint by sending an arbitrarily large request body. This can cause the service to consume excessive memory, leading to memory exhaustion, degraded responsiveness, and a denial of service (DoS) condition.
