Description
CVE-2026-97027 is a vulnerability in Flatpak on Red Hat Enterprise Linux 10 where arbitrary vendor-extension keys are passed through unvalidated when exporting Desktop Entry and D-Bus Service files. This allows a malicious Flatpak application to cause denial of service conditions such as forced application restart loops or to influence host D-Bus/systemd activation behavior beyond the intended sandbox restrictions. The vulnerability requires local user interaction to install and run a malicious Flatpak app. The impact is limited to availability with no confidentiality or integrity effects.
