Why flagged

This PKGBUILD downloads a prebuilt binary package (.pkg.tar.zst) from x11libre.net, which is a personal/unofficial host rather than an official Arch Linux mirror, GitHub releases, or a well-known vendor CDN. The package then extracts and installs the binary directly into the system (specifically the 'usr' tree), meaning arbitrary compiled code from this third-party host gets executed/loaded at runtime as an X.Org video driver. While XLibre is a known X.Org fork and the sha256sum provides some integrity guarantee, the trust anchor is entirely the x11libre.net host operator — if that host is compromised or the maintainer is malicious, users get a backdoored GPU driver running with X server privileges. There is no GPG signature verification, no reference to a canonical upstream release page, and the binary is not built from source. This is a textbook supply-chain risk: an executed binary from an unofficial/personal host, which warrants MEDIUM severity.

Triggered rules

Medium source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
