Oct 11 PATCH SHIPPED — CVE-2026-96275 (Red Hat Enterprise Linux 10). Fixed in Red Hat Enterprise Linux 10 0:1.16.0-9.el10_2.4.
Description
A malicious or compromised Flatpak repository can write attacker-controlled content to arbitrary locations on the host filesystem via extract_extra_data(). On system installs, the write happens as root. Two issues combine: `files/extra` is resolved via path operations that follow symlinks, and blob names from `xa.extra-data-sources` are not sanitized against `..` traversal.
