Passing NULL to hcd_to_vhci_hcd() does not\nreturn NULL - it returns a pointer offset of 0x260, causing a NULL\npointer dereference when that value is subsequently dereferenced.\n\nAdd a NULL check on hcd before calling hcd_to_vhci_hcd(). Move\nstatus_show_not_ready() above status_show_vhci() to make it callable\nfrom the new error path without a forward declaration.\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":[]}
