iOS and iPadOS: Uncontrolled Resource Consumption

Published Updated By the CyberSecBulletin desk

CVE-2025-24190 is a critical-severity uncontrolled resource consumption vulnerability in iOS and iPadOS from Apple, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 18.4 as the first without the flaw, so updating iOS and iPadOS to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.92% chance of exploitation within 30 days, higher than 80% of scored CVEs.

The underlying weakness: Uncontrolled Resource Consumption

The product does not properly control the allocation and maintenance of a limited resource.

How developers prevent this class of flaw

  • Ensure that protocols have specific limits of scale placed on them.
  • Ensure that all failures in resource allocation place the system into a safe posture.
