That is the policy for *using* an object, and using an object a module does not own is supported and intended — `txm_module_object_pointer_get_extended` searches the system's created objects by name and hands back objects the application created and objects other modules created, so that a module can send to a shared queue, take a shared semaphore or get a shared mutex.\n\n\n\nDestroying one of those is not sharing it. A module could name any object it had a pointer to and have the privileged dispatcher delete it.\n\n## Affected\n\n- `ThreadX >= 6.0.1 <= 6.5.1.202602a`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":38,"depthScoreParts":{"impact":38,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
