Why flagged

This PKGBUILD downloads a prebuilt binary package (a compiled X.org video driver) from x11libre.net, which is a self-hosted distribution mirror rather than the upstream GitHub repository (github.com/X11Libre). The binary is then extracted and installed directly into the package directory. While a sha256sum is provided, this only protects against accidental corruption or a one-time swap — it does not protect against the host serving a malicious binary from the start, nor against future checksum updates in the PKGBUILD pointing to a compromised binary. The core concern is that a prebuilt kernel/X.org driver binary from a personal/project-controlled host (not a well-known, audited mirror) is being installed into a privileged location and loaded by the X server, giving it significant system access. XLibre is a real fork of X.Org (https://github.com/X11Libre exists), so this is not clearly malicious, but the pattern of bypassing source builds in favor of opaque binaries from a self-hosted server is a genuine supply-chain risk that 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, …).
