iOS and iPadOS: Access of Resource Using Incompatible Type
CVE-2025-24129 is a high-severity access of resource using incompatible type vulnerability in iOS and iPadOS from Apple, with a CVSS 3.1 base score of 7.5 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 18.3 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 1.31% chance of exploitation within 30 days, higher than 71% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update iOS and iPadOS to 18.3 or a later version.
- Update macOS to 13.7.5 or 14.7.5 or 15.3, whichever matches your release line, or a later version.
- Update tvOS to 18.3 or a later version.
- Read the advisory on support.apple.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
