Why flagged

This PKGBUILD downloads and installs a prebuilt binary X.Org/XLibre video driver from x11libre.net, a non-standard third-party host. The binary is extracted directly into the package directory (usr/ tree), meaning it will install compiled shared libraries and potentially kernel-interfacing code that runs with X server privileges. While x11libre.net appears to be the official host for the XLibre project (a fork of X.Org), it is not an established, widely-trusted distribution channel like upstream vendor releases or major language ecosystem mirrors. There is no GPG signature verification — only a sha256sum — meaning if the host is compromised or the file is substituted, the only protection is the hash. The sha256sum does provide integrity checking against the specific known-good file, which mitigates (but does not eliminate) supply-chain risk. The concern is real but not clearly malicious: a prebuilt binary X driver from a personal/small-project host with no signature verification is a genuine medium-severity supply-chain concern.

Triggered rules
