And add comment above get_dvsec_vendor0() to tell\ncallers to call pci_dev_put().\n\n## Affected\n\n- `Linux >= 87db7579ebd5ded337056eb765542eb2608f16e3 < a40e1b0a922a53fa925ea8b296e3de30a31ed028`\n- `Linux >= 87db7579ebd5ded337056eb765542eb2608f16e3 < 37a13b274e4513c757e50c002ddcbf4bc89adbb2`\n- `Linux >= 87db7579ebd5ded337056eb765542eb2608f16e3 < 9a1b3148975b71fdc194e62612478346bbe618cd`\n- `Linux >= 87db7579ebd5ded337056eb765542eb2608f16e3 < 40ff4c2335a98f0ee96b099bfd70b8e6644f321f`\n- `Linux >= 87db7579ebd5ded337056eb765542eb2608f16e3 < 27158c72678b39ee01cc01de1aba6b51c71abe2f`\n- `Linux 5.9`\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":[]}
