View on AUR
Why flagged

The source is a driver from the official Sunix website, hosted on a non-whitelisted but plausibly legitimate domain; it is a standard kernel module build with no evidence of malicious behavior or unverifiable prebuilt binaries.

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 source is a driver from the official Sunix website, hosted on a non-whitelisted but plausibly legitimate domain; it is a standard kernel module build with no evidence of malicious behavior or unverifiable prebuilt binaries.

1 higher static finding superseded - not the current verdict (shown for transparency)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