Research direction
Start by locating the Docker image or base-image configuration that supplies OpenSSL, then inspect how the published image is built. Verify the affected image contains OpenSSL 3.5.6 and determine the smallest update path to a release containing the cited fix. Done means the image uses a fixed OpenSSL release and the resulting version is verified in the container.
