| Doc Text: |
A flaw was found in BuildKit. A local user with build permissions can trigger a Denial of Service (DoS) by submitting a build context containing an oversized Dockerfile or .dockerignore file. Because the Dockerfile frontend loads these files directly into memory without enforcing a size limit, an excessively large file can exhaust system memory and terminate the build daemon. This termination halts all other active build processes running on the same instance.
