CVE-2026-97027: Red Hat Enterprise Linux 10

Low severity, CVSS 3.6. EPSS: 0.1% chance of exploitation in the next 30 days.

Flatpak passes through arbitrary vendor-extension keys unmodified when exporting an application's Desktop Entry (.desktop) and D-Bus Service (.service) files, instead of validating against an allowlist. A malicious Flatpak app can use this to cause denial of service (e.g. forced application restart loops) or to influence host D-Bus/systemd activation behavior beyond what the sandbox is intended to permit.

Affected products

• Red Hat Red Hat Enterprise Linux 10
