This results in use-after-free.\n\nIf atomisp_register_i2c_module() fails, the media entity and control\nhandler are left initialized and dev is leaked.\n\ngc2235_remove() unconditionally calls media_entity_cleanup() and\nv4l2_ctrl_handler_free(), but these are not initialized at every\nerror path in gc2235_probe().\n\nReplace gc2235_remove() calls in the probe error paths with explicit\nunwind labels that free only the resources initialized at each point\nof failure, in reverse order of initialization.\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":[]}
