Analysis Summary
As a vulnerability research specialist, here is the summarized, actionable intelligence based on the provided context:
# Vulnerability: Actively Exploited Use-After-Free in Apple Core Media
## CVE Details
- CVE ID: CVE-2025-24085
- CVSS Score: Not explicitly stated, but marked as **Actively Exploited Zero-Day**. (Implies High/Critical severity)
- CWE: Use-After-Free (UAF)
## Affected Systems
- Products: iOS, iPadOS, macOS, tvOS, visionOS, watchOS.
- Versions: Versions of iOS *before* iOS 17.2 (for reports of prior exploitation in the wild).
- Configurations: Requires a malicious application already installed on the device.
## Vulnerability Description
The vulnerability, tracked as CVE-2025-24085, is a **use-after-free (UAF) bug** residing in the **Core Media** component. Successful exploitation allows a malicious, pre-installed application on the device to perform **privilege escalation**.
## Exploitation
- Status: **Actively exploited in the wild** (Confirmed by Apple advisory regarding iOS versions before 17.2).
- Complexity: Likely Low/Medium, given the active exploitation and the fact it allows escalation from an already installed application.
- Attack Vector: Local (via the malicious installed application).
## Impact
- Confidentiality: Potentially High (due to successful privilege escalation).
- Integrity: Potentially High (due to successful privilege escalation).
- Availability: Unknown, but high privilege context increases overall risk.
## Remediation
### Patches
Apple addressed this issue with improved memory management across multiple platforms:
* **iOS/iPadOS:** Versions **18.3** and later (Affects iPhone XS+, various recent iPads).
* **macOS:** Version **Sequoia 15.3** and later.
* **tvOS:** Version **18.3** and later.
* **visionOS:** Version **2.3** and later.
* **watchOS:** Version **11.3** and later.
### Workarounds
No specific workarounds are detailed in the provided summary, but generally restricting application installation sources is beneficial.
## Detection
- **Indicators of Compromise (IoCs):** Details on specific in-the-wild exploitation IoCs are not provided in this summary.
- **Detection Methods and Tools:** Monitoring device behavior for unauthorized privilege changes or anomalies originating from existing applications should be prioritized. Apple's security updates often include kernel-level mitigations which standard endpoint detection tools should leverage post-patching.
