CVE-2025-24085 is an use-after-free vulnerability in Apple Multiple Products. CISA added it to the Known Exploited Vulnerabilities catalogue on 29 January 2025, which means attackers have used it in real attacks. Apple iOS, macOS, and other Apple products contain a user-after-free vulnerability that could allow a malicious application to elevate privileges.
What a use-after-free vulnerability means in Apple products
A use-after-free flaw occurs when software keeps using memory after it has been released. In Apple iOS, macOS, and related products, that kind of memory-safety failure can let a malicious app trigger unexpected behaviour and potentially gain higher privileges than it should have.
This is dangerous because the bug sits inside the trust boundary of the operating system or a core component, not merely inside one isolated app. A successful exploit can turn normal application access into broader system access, which is why memory corruption issues are often treated as high-value targets for attackers.
Why this vulnerability class is security-relevant
Use-after-free issues are especially important in managed platforms because they can be chained with other bugs to get code execution, privilege escalation, or sandbox escape. The exploitability depends on how reliably an attacker can control memory reuse, but the consequence is usually much more severe than a simple application crash.
Apple products are broadly deployed across consumer and enterprise environments, so a flaw in a common platform can have a wide blast radius. When the vulnerable component is shared across devices, one weakness can affect many endpoints at once, which makes prioritisation important for vulnerability management teams.
How organisations assess exposure
Exposure review starts with asset inventory, OS version visibility, and understanding which Apple devices are internet-facing or reachable by untrusted content. For a live CVE, organisations should check the vendor advisory and the NIST National Vulnerability Database entry to confirm the affected product scope and follow the CVE Program record for canonical identification.
For prioritisation, the most useful questions are whether the vulnerable devices are exposed to untrusted apps, whether users can install or open untrusted content, and whether the product is used for privileged workflows. A vulnerability becomes more urgent when the affected system is both widely deployed and difficult to isolate.
Remediation, detection, and post-exploitation review
The primary remediation path is vendor patching, but if patching must wait, compensating controls should reduce attacker opportunity by limiting untrusted software, tightening endpoint permissions, and increasing monitoring on the affected platform. The broader remediation model used for exploited vulnerabilities is well captured in the Vulnerability Management Guide, which frames asset scope, prioritisation, exceptions, and verification as part of the lifecycle.
After patching, organisations should still review for signs of compromise if exploitation was plausible or observed. That review should look for unexpected privilege changes, suspicious app behaviour, crash patterns around the vulnerable component, and any persistence established before the fix was applied.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
MITRE ATT&CK addresses the attack surface, NIST CSF 2.0, NIST SP 800-53 Rev 5 and CIS Controls v8 set the technical controls, and ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | ID.RA-01 — Asset Vulnerability Identification | Use-after-free vulnerabilities require identifying exposure across Apple assets and versions. |
| Recommendation — Map affected Apple devices and exposure paths to ID.RA-01 and prioritise remediation by asset risk. | ||
| NIST SP 800-53 Rev 5 | SI-2 — Flaw Remediation | This CVE is remediated through timely flaw handling and verification after patching. |
| Recommendation — Apply SI-2 to track, patch, and verify remediation for the Apple vulnerability. | ||
| CIS Controls v8 | CIS-7 — Continuous Vulnerability Management | The issue is a live, exploited vulnerability that fits continuous vulnerability management. |
| Recommendation — Use CIS-7 to prioritise exposed Apple systems and validate that remediation actually landed. | ||
| MITRE ATT&CK | T1068 — Exploitation for Privilege Escalation | The vulnerability can allow a malicious application to elevate privileges. |
| Recommendation — Map indicators of successful exploitation to T1068 and hunt for privilege-escalation behaviour. | ||
| ISO/IEC 27001:2022 | A.8.8 — Management of technical vulnerabilities | Technical vulnerability management directly applies to a KEV-listed Apple flaw. |
| Recommendation — Use A.8.8 to govern identification, prioritisation, remediation, and verification of the Apple CVE. | ||
Practitioner Guidance
Why practitioners should care: A use-after-free CVE is not just a stability issue, it can be a privilege-escalation path that changes endpoint trust assumptions. Treat it as a security exposure on the platform itself, not as an isolated application defect.
What to watch for: Prioritise devices that run exposed or high-trust Apple workloads, especially where users can interact with untrusted applications or content. If exploitation is suspected, verify whether the device shows unusual privilege activity or application instability before assuming the patch alone is enough.
