iOS and iPadOS: Protection Mechanism Failure
CVE-2024-44122 is a high-severity protection mechanism failure vulnerability in iOS and iPadOS from Apple, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 18 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 0.26% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update iOS and iPadOS to 18 or a later version.
- Update macOS to 13.7.1 or 14.7.1 or 15, whichever matches your release line, or a later version.
- Read the advisory on support.apple.com for workarounds and exact fixed builds.
