iOS and iPadOS: Access of Resource Using Incompatible Type
CVE-2025-24137 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 8.0 out of 10. It can be exploited from the same local network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. 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 0.95% chance of exploitation within 30 days, higher than 62% 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 iPadOS to 17.7.4 or a later version.
- Update macOS to 14.7.3 or 15.3, whichever matches your release line, or a later version.
- Read the advisory on support.apple.com for workarounds and exact fixed builds.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
