LOW

Why flagged

The package sets setuid permissions on bundled sandbox helper binaries (glxtest, vaapitest) during packaging, which triggers the rule, but this is a common practice for browser sandboxing and not inherently malicious.

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-2507) reviewed the full PKGBUILD and judged it LOW (confidence 95%): The package sets setuid permissions on bundled sandbox helper binaries (glxtest, vaapitest) during packaging, which triggers the rule, but this is a common practice for browser sandboxing and not inherently malicious.

1 higher static finding superseded - not the current verdict (shown for transparency)

Medium Privileged / out-of-pacman install (sudoers, setuid, or self-update) privileged_install

The package grants elevated privileges or installs an update path outside pacman: a /etc/sudoers.d rule (often passwordless), a setuid/setgid binary, or a self-update script/service that can fetch and run future code with no checksum verification. The initial install may be verified, but the ongoing privilege + update surface is a real supply-chain / privilege-escalation risk.
