Red Hat Enterprise Linux: denial of service
Low3.9CVE-2026-97026 · Published Sep 28, 2026 · updated Sep 30, 2026
Flatpak creates temporary child repository directories under the user cache with world-writable permissions (0777). On multi-user systems with a permissive umask, other local users could read or modify the temporary directory used while installing apps or runtimes, potentially causing installation failures (denial of service); tampered content would fail signature/digest verification rather than being trusted.
