If off->val.tv_nsec\ncontains invalid values (negative or >= NSEC_PER_SEC), it could lead to\nincorrect calculations or unexpected behavior.\n\nAdd validation to ensure tv_nsec is within the valid range before\nperforming the addition.\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":[]}
