Real-World Exposure
github.com/moby/buildkitReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Impact
A malicious BuildKit client or frontend could craft a request that could lead to BuildKit daemon crashing with a panic.
Patches
The issue has been fixed in v0.12.5
Workarounds
Avoid using BuildKit frontends from untrusted sources. A frontend image is usually specified as the #syntax line on your Dockerfile, or with --frontend flag when using buildctl build command.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/moby/buildkit, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/moby/buildkit to 0.12.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-23650 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
Avoid using untrusted input for the client or frontend syntax to minimize the vulnerability exploration.Source: Red Hat security advisory for CVE-2024-23650 (CC BY 4.0)
