Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This is a use-after-free vulnerability caused by improper memory management. An app could exploit this to cause unexpected system termination by accessing memory after it has been freed.

Detection Guidance

This vulnerability is a use-after-free issue in Apple operating systems. Detection typically requires analyzing memory management patterns in running applications. Use system monitoring tools like Activity Monitor (macOS) or built-in security logs to check for unexpected app terminations. For advanced detection, use memory analysis tools such as dtrace or valgrind on affected systems.

Impact Analysis

An attacker could potentially crash your device or cause it to become unresponsive by exploiting this flaw in a malicious app.

Compliance Impact

The vulnerability involves a use-after-free issue that could cause unexpected system termination. This may lead to data loss or corruption, which could impact compliance with GDPR (data integrity) and HIPAA (availability of protected health information). However, the provided CVE details do not explicitly address compliance implications.

Mitigation Strategies

Update affected Apple devices to the latest versions mentioned in the CVE description to address the use after free issue.
