CVE-2026-96284 Red Hat CVE debrief

A CVE record was published for a vulnerability in the flatpak-system-helper context. A malicious user can get read-access to files if a system OCI repository is configured, because the OCI code paths in the system helper follow symlinks when importing OCI images that are under the user's control. Defenders responsible for OCI repository configurations and Flatpak deployments should assess exposure and prioritize verification of their systems. The vulnerability exists in the flatpak-system-helper context, where a malicious user can gain read-access to files if a system OCI repository is configured. The OCI code paths in the system helper follow symlinks when importing OCI images. To
