So call to 'kobject_put()' on error handling\npath causes an attempt to use an uninitialized completion pointer in\n'module_kobject_release()'. In this scenario, we just want to release\nkobject without an extra synchronization required for a regular module\nunloading process, so adding an extra check whether 'complete()' is\nactually required makes 'kobject_put()' safe.\n\n## Affected\n\n- `Linux >= 942e443127e928a5631c3d5102aca8c8b3c2dd98 < 93799fb988757cdacf19acba57807746c00378e6`\n- `Linux >= 942e443127e928a5631c3d5102aca8c8b3c2dd98 < a63d99873547d8b39eb2f6db79dd235761e7098a`\n- `Linux >= 942e443127e928a5631c3d5102aca8c8b3c2dd98 < f1c71b4bd721a4ea21da408806964b10468623f2`\n- `Linux >= 942e443127e928a5631c3d5102aca8c8b3c2dd98 < 9e7b49ce4f9d0cb5b6e87db9e07a2fb9e754b0dd`\n- `Linux >= 942e443127e928a5631c3d5102aca8c8b3c2dd98 < faa9059631d3491d699c69ecf512de9e1a3d6649`\n- `Linux >= 942e443127e928a5631c3d5102aca8c8b3c2dd98 < d63851049f412cdfadaeef7a7eaef5031d11c1e9`\n- `Linux >= 942e443127e928a5631c3d5102aca8c8b3c2dd98 < 31d8df3f303c3ae9115230820977ef8c35c88808`\n- `Linux >= 942e443127e928a5631c3d5102aca8c8b3c2dd98 < a6aeb739974ec73e5217c75a7c008a688d3d5cf1`\n- `Linux 3.12`\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":[]}
