However, the implementation simply breaks\nfrom a switch statement and leaks uninitialized return code `rc' (if the\nfirst section is a security one) or the previous section's `rc'.\n\nFix it by really skipping a loop with `continue'. For consistency and\nreadability, also do the same for the default case.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
