LOW

Why flagged The package downloads prebuilt toolchain tarballs from toolchains.bootlin.com, a known and legitimate embedded Linux toolchain provider, and installs them with verified checksums; while the host is not universally whitelisted, the content is legitimate build tooling used in a standard way, posing minimal supply-chain risk.

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 prebuilt toolchain tarballs from toolchains.bootlin.com, a known and legitimate embedded Linux toolchain provider, and installs them with verified checksums; while the host is not universally whitelisted, the content is legitimate build tooling used in a standard way, posing minimal supply-chain risk.

1 higher static finding superseded - not the current verdict (shown for transparency)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