- Red Hat GNOME Remote Desktop 0.1.6-1 through 40.0-11.
- Is there a fix for CVE-2026-109832?
- No fixed version is recorded yet. If VNC is not required, disable the gnome-remote-desktop VNC service. If it must remain enabled, restrict the VNC listener to trusted hosts or management networks using host-based firewall rules. If you run it, Junglewise drafts a mitigation that fits your setup and applies it once you approve, with senior security engineers behind it.
- How is CVE-2026-109832 attacked?
- It is attacked over the network, in a hosted service.
- Am I affected by CVE-2026-109832?
- Check whether you run Red Hat GNOME Remote Desktop at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.
How to fix
If VNC is not required, disable the gnome-remote-desktop VNC service. If it must remain enabled, restrict the VNC listener to trusted hosts or management networks using host-based firewall rules.
Technical details
The vulnerability is an infinite loop (CWE-835) in the VNC TLS I/O handlers that occurs when GnuTLS returns retryable error codes (GNUTLS_E_AGAIN or GNUTLS_E_INTERRUPTED). Instead of yielding to the event loop, the code spins indefinitely, consuming CPU resources with no forward progress. A remote, unauthenticated attacker who can reach the VNC listener can exploit this without privileges or user interaction.
