If the\nlength of the device path exceeds the output buffer length, the function\nreturns -ENOSPC but does not free the allocated memory, resulting in a\nmemory leak.\n\nAdd a kfree() call to the error path to ensure the allocated memory is\nproperly freed.\n\nCompile tested only. Issue found using a prototype static analysis tool\nand code review.\n\n## Affected\n\n- `Linux >= ec7ad6530909983c8736c80af46e3529ce7bab55 < ee998cdbff6680891b0efd9d6ce53a388e5342c3`\n- `Linux >= ec7ad6530909983c8736c80af46e3529ce7bab55 < b2bc649c18fbe8a7fd38d17266da3dcbfbcc44d2`\n- `Linux >= ec7ad6530909983c8736c80af46e3529ce7bab55 < b3a10eca24fcfe913c0875e620f19596001bd6dc`\n- `Linux >= ec7ad6530909983c8736c80af46e3529ce7bab55 < 9b9d253908478f504297ac283c514e5953ddafa6`\n- `Linux 6.12`\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":[]}
