The error path would then call\nmtk_free_dev(), which in turn called free_netdev() assuming dummy_dev\nwas allocated (but it was not), potentially causing a NULL pointer\ndereference.\n\nBy moving free_netdev() to mtk_remove(), we ensure it's only called when\nmtk_probe() has succeeded and dummy_dev is fully allocated. This\naddresses a potential NULL pointer dereference detected by Smatch[1].\n\n## Affected\n\n- `linux_kernel >= 6.10, < 6.10.3`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.10.3`","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
