The AlmaLinux 9.2 host has a package installed that is affected by a vulnerability as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1788817207 advisory.

  - A flaw was found in dbus-broker. When the process file-descriptor limit is reached, EMFILE/ENFILE errors     during peer setup (notably SO_PEERPIDFD) are handled as fatal failures, causing the broker to exit. A     local attacker who can open many connections to the user session bus can trigger this and deny service to     the desktop session. Flatpak applications can reach the host session bus through the dbus proxy.
    (CVE-2026-16730)
