CVE-2024-44227 Overview
CVE-2024-44227 is a memory handling vulnerability affecting Apple iOS, iPadOS, and macOS. The flaw allows a malicious application to cause unexpected system termination or corrupt kernel memory. Apple addressed the issue with improved memory handling in iOS 18, iPadOS 18, and macOS Sequoia 15. The vulnerability is classified under [CWE-400] Uncontrolled Resource Consumption.
Critical Impact
An app can trigger kernel memory corruption or unexpected system termination, leading to denial of service conditions on affected Apple devices.
Affected Products
- Apple iOS (versions prior to iOS 18)
- Apple iPadOS (versions prior to iPadOS 18)
- Apple macOS (versions prior to macOS Sequoia 15)

Technical Details for CVE-2024-44227
Vulnerability Analysis
The vulnerability stems from improper memory handling within Apple's operating system kernel. An application running on the device can exploit this weakness to corrupt kernel memory regions or trigger an unexpected system termination. The flaw is categorized as [CWE-400] Uncontrolled Resource Consumption, which indicates that the affected code path fails to properly constrain memory operations.
Successful exploitation impacts system integrity by allowing kernel memory corruption. While the public advisory does not detail the specific subsystem affected, kernel memory corruption issues on Apple platforms typically arise in IPC handlers, driver interfaces, or syscall boundary code paths.
Root Cause
The root cause is insufficient memory handling logic in the affected Apple operating system components. Apple's fix involved improved memory handling routines, indicating that the prior implementation lacked adequate bounds enforcement or resource management when processing untrusted input from user-space applications.
Attack Vector
Exploitation requires a malicious or compromised application to execute on the target device. The attacker-controlled app issues crafted requests or operations that trigger the flawed memory handling path within the kernel. No user interaction beyond running the malicious app is required for exploitation.
No verified proof-of-concept code is publicly available for CVE-2024-44227. Refer to the Apple Support Article #121238 and Apple Support Article #121250 for vendor-provided technical context.
Detection Methods for CVE-2024-44227
Indicators of Compromise
- Unexpected kernel panics or system reboots on iOS, iPadOS, or macOS devices running unpatched versions.
- Crash logs referencing kernel memory access violations or memory corruption signatures.
- Anomalous application behavior immediately preceding system termination events.
Detection Strategies
- Inventory all Apple devices and identify those running iOS, iPadOS, or macOS versions below the patched releases.
- Review MDM and endpoint telemetry for OS version compliance against iOS 18, iPadOS 18, and macOS Sequoia 15.
- Collect and analyze device crash reports for repeated kernel panics correlated with specific applications.
Monitoring Recommendations
- Enable centralized crash log collection from managed Apple endpoints through your MDM platform.
- Monitor application installation events on managed devices to identify untrusted or sideloaded apps.
- Correlate device reboot patterns with application usage to identify potential exploitation attempts.
How to Mitigate CVE-2024-44227
Immediate Actions Required
- Update all iPhone devices to iOS 18 or later through Settings, General, Software Update.
- Update all iPad devices to iPadOS 18 or later.
- Update all Mac devices to macOS Sequoia 15 or later.
- Restrict installation of untrusted applications, especially on enterprise-managed devices.
Patch Information
Apple released patches for this vulnerability in iOS 18, iPadOS 18, and macOS Sequoia 15. Patch details are documented in Apple Support Article #121238 and Apple Support Article #121250. Apply these updates through standard MDM workflows or end-user software update mechanisms.
Workarounds
- No official workarounds are provided by Apple beyond applying the security updates.
- Limit application installation to vetted sources such as the Apple App Store and enterprise-approved catalogs.
- Enforce OS version compliance policies through MDM to block enrollment of unpatched devices.
