Miggo AIRoot Cause AnalysisThe vulnerability stems from improper validation of the HOME environment variable in CRI-O's container creation process. The GitHub pull request #6450 explicitly shows the fix was implemented in server/container_create.go by adding a check for newline characters (\n) in the HOME variable. The vulnerable versions lacked this validation, enabling the injection of arbitrary entries into /etc/passwd. The setupContainerUser function is directly responsible for handling environment variables and user setup, making it the clear vulnerable component.
