LOW

Why flagged The package downloads a source archive from the official vendor's website (siliconmotion.com), which is the legitimate provider of the driver; the non-standard host flag is a false positive as the domain is authentic and the content is a self-extracting installer for a proprietary userspace daemon, not untrusted executable code.

Triggered rules

LOW AI review downgraded a static finding llm_review

The static rules flagged this MEDIUM, but an AI model (qwen/qwen3-235b-a22b-07-25) reviewed the full PKGBUILD and judged it LOW (confidence 95%): The package downloads a source archive from the official vendor's website (siliconmotion.com), which is the legitimate provider of the driver; the non-standard host flag is a false positive as the domain is authentic and the content is a self-extracting installer for a proprietary userspace daemon, not untrusted executable code.

1 higher static finding superseded - not the current verdict (shown for transparency)

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, …).
