The helper increments the global hif_idx, writes the\nPCIe RECOG_ID register and takes a get_device() reference via\nmt7915_pci_get_hif2(), while removal only drops one reference. On non-WED\ndual-hif hardware this double-incremented hif_idx, wrote RECOG_ID twice and\nleaked a device reference. Only the call inside the WED-inactive branch is\ncorrect; drop the unconditional one. hif2 is already initialised to NULL.\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":[]}
