The helper returns the child's stashed skb first and is a no-op\nwhen there is none, so a work-conserving child is unaffected and the\ngated path now consumes the skb whose length was charged to the budget.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":45,"depthScoreParts":{"impact":45.1,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
