Unfortunately both\ncallbacks have the very same form, and the compiler didn't complain\nit, either.  This resulted in a NULL dereference because the PCM\ninstance hasn't been initialized at calling the build_controls\ncallback.\n\nFix it by passing the proper entries.\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":[]}
