Apple iOS, macOS, iPadOS Use-After-Free Vulnerability (CVE-2025-24085) Technical Analysis and Urgent Patch Advisory

1. Vulnerability Overview & Root Cause

This vulnerability (CVE-2025-24085) is a critical Use-After-Free (UAF) flaw residing in the memory management component of various Apple operating systems. It occurs when a program continues to use a pointer after the memory block it references has been deallocated. Due to improper memory management, an attacker can manipulate the freed memory space, leading to memory corruption and arbitrary code execution under elevated privileges.

2. Exploitation Mechanics & Attack Scenario

An attacker can exploit this vulnerability by executing a specially crafted malicious application on the target device. The local malicious app triggers the premature release of a specific system memory object and subsequently fills that memory address with attacker-controlled payloads. When the operating system attempts to reuse or dereference the stale pointer, it executes the attacker's payload, bypassing application sandboxing and achieving full kernel-level privilege escalation.

3. Infrastructure & Business Impact

With a CVSS score of 10.0, this vulnerability poses an extreme risk. It has been added to the CISA KEV list due to active exploitation in the wild, particularly targeting iOS versions prior to iOS 17.2. In an enterprise environment, successful exploitation allows threat actors to compromise corporate mobile devices and workstations, leading to sensitive data exfiltration, credential theft, and potential lateral movement within the corporate network.
