After the loop,\ndocg3->cascade->bch dereferences the already-freed pointer.\n\nFix this by accessing cascade->bch directly, which is equivalent\nsince docg3->cascade points back to the same cascade struct, and\nis already available as a local variable. This also removes the\nnow-unused docg3 local variable.\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":[]}
