An issue was discovered in certain Apple products. iOS before 11.2.5 is affected. macOS before 10.13.3 is affected. watchOS before 4.2.2 is affected. The issue involves the "LinkPresentation" component. It allows remote attackers to cause a denial of service (resource consumption) via a crafted text message.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
