Red Hat advises running Flatpak apps in a new session (e.g., using 'setsid flatpak run ...') or a new process group (e.g., using setpgid(0, 0) in the parent process). Avoid running untrusted Flatpak applications.
Description
CVE-2026-97029 is a vulnerability in Flatpak's process ID namespace separation on Red Hat Enterprise Linux 10. It allows a sandboxed Flatpak application to send kill signals to processes outside its sandbox if they share the same process group. This can lead to denial of service by terminating critical processes such as the desktop shell, disrupting the user's session. The vulnerability requires the user to run a malicious or compromised Flatpak app. There is no confidentiality or integrity impact, but availability impact is high due to potential session termination.
