However, as\ndivision by zero errors can cause system failure, for defense measure,\nthe value of max_speed is validated here. So 0 is regarded as invalid\nand an error code is returned.\n\n## Affected\n\n- `Linux >= c770d8631e1810d8f1ce21b18ad5dd67eeb39e5c < dc30f8d9b25db3b79d36971a90c1ee95010ff45a`\n- `Linux >= c770d8631e1810d8f1ce21b18ad5dd67eeb39e5c < 16ccaf581da4fcf1e4d66086cf37263f9a656d43`\n- `Linux >= c770d8631e1810d8f1ce21b18ad5dd67eeb39e5c < ee73a15d4a8ce8fb02d7866f7cf78fcdd16f0fcc`\n- `Linux >= c770d8631e1810d8f1ce21b18ad5dd67eeb39e5c < 5127c42c77de18651aa9e8e0a3ced190103b449c`\n- `Linux 5.13`\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":[]}
