MEDIUM

Why flagged This PKGBUILD downloads a prebuilt binary package (a compiled Xorg video driver .pkg.tar.zst) from x11libre.net, a personal/project host that is not an official Arch Linux mirror or well-known vendor CDN. The binary is then extracted and installed directly into the package directory. While a sha256sum is present, it only protects against accidental corruption or a one-time swap — it provides no cryptographic authenticity guarantee (no GPG signature verification). The core concern is that a prebuilt, executed binary (an Xorg DDX driver loaded into the X server process) is sourced from an unofficial third-party host. If x11libre.net were compromised or the domain transferred, a malicious binary could be substituted with a new matching checksum pushed to the PKGBUILD. The XLibre project is a real X.Org fork, but distributing prebuilt binaries from a personal project host rather than building from source is a genuine supply-chain risk for executed code. This is a textbook medium-severity concern.
