On August 25, 2026, Fedora released a security update for FreeIPA and Samba, specifically updating to Samba version 4.24.6.

The update addresses several vulnerabilities, including CVE-2026-11861, CVE-2026-13097, CVE-2026-19550, CVE-2026-73199, CVE-2026-73198, and CVE-2026-73197, which were published between August 11 and August 20, 2026. These vulnerabilities include issues such as unauthorized LDAP writes and denial-of-service (DoS) conditions. Users are advised to apply the update using the 'dnf' package manager to mitigate potential risks associated with these vulnerabilities. The update does not introduce new features or changes but is crucial for maintaining system integrity during upgrades.
