An\nidle poll therefore reports a full budget and remains scheduled.\n\nReturn the number of received packets instead. Preserve the existing\nfree queue refill accounting by adding that count directly; continuing\nto subtract it from the budget would invert the refill behavior.\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":[]}
