Missing evidence does not mean no public exploit exists.

Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

A malicious user can get read-access to files in the flatpak-system-helper context if a system OCI repository is configured. The vulnerability is due to the OCI code paths in the system helper following symlinks when importing OCI images under the user's control. This affects Red Hat Enterprise Linux 7, 8, 9, and 10.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.
