It does not undo\nthe successful cpsw_register_devlink() call, leaving the devlink instance\nand its parameters registered after probe has failed.\n\nAdd a devlink cleanup label for the path where devlink registration has\nalready succeeded, and use it when port registration fails.\n\n## Affected\n\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < b020390b4ef39adc40c800301042baf812280da1`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 5a5ac0defdd42e566f1c871272370b6a3a8eef5c`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 43d4af5c5331ea739a49cb1097d41e502ed91ec4`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 8af61d5bd87fd1a3bdc81fe948e7acdc8aa5bcf0`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 2bcf21ede6b097ca96cb1f7679761acca6510555`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 0a44945b0d3422f5d81b49c97e293f3e21a8c585`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < b64f763b607426ac97e44b114f0b8844ac3b86dd`\n- `Linux < 5.10.271`\n- `Linux < 5.15.222`\n- `Linux < 6.1.189`\n- `Linux < 6.6.158`\n- `Linux < 6.12.111`\n- `Linux < 6.18.53`\n- `Linux (all versions)`\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":[]}
