Full Report
Multiple vulnerabilities have been discovered in Apple products, the most severe of which could allow for arbitrary code execution. Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
Analysis Summary
# Vulnerability: Multiple Apple OS Arbitrary Code Execution and Privilege Escalation
## CVE Details
- **CVE ID:** CVE-2026-28819 (Critical), CVE-2026-43668, CVE-2026-28951, CVE-2026-28915 (and others)
- **CVSS Score:** Estimated 7.8 - 9.8 (High to Critical)
- **CWE:** CWE-20 (Improper Input Validation), CWE-119 (Memory Corruption), CWE-264 (Permissions/Privilege)
## Affected Systems
- **Products:** iOS, iPadOS, macOS (Tahoe, Sequoia, Sonoma), tvOS, watchOS, visionOS.
- **Versions:**
- iOS/iPadOS: Prior to 26.5, 18.7.9, 16.7.16, and 15.8.8
- iPadOS: Prior to 17.7.11
- macOS Tahoe: Prior to 26.5
- macOS Sequoia: Prior to 15.7.7
- macOS Sonoma: Prior to 14.8.7
- tvOS, watchOS, visionOS: Prior to 26.5
- **Configurations:** Systems running with administrative privileges are at higher risk.
## Vulnerability Description
Multiple flaws exist across Apple's kernel and media processing frameworks. The most severe, **CVE-2026-28819**, allows a malicious application to execute arbitrary code with kernel-level privileges. Other critical flaws involve memory corruption during the processing of maliciously crafted images or media files, which can lead to process memory corruption or unexpected system termination. Additionally, multiple vulnerabilities allow applications to bypass sandboxes or escalate privileges to root.
## Exploitation
- **Status:** Not exploited in the wild (as of advisory date); no public PoC currently reported.
- **Complexity:** Medium (requires user interaction or local app installation).
- **Attack Vector:** Various (Network for remote media flaws; Local for privilege escalation; Physical for iPhone Mirroring flaws).
## Impact
- **Confidentiality:** High (Access to sensitive user data and kernel memory).
- **Integrity:** High (Ability to install programs, modify data, and create accounts).
- **Availability:** High (Denial-of-Service and kernel panics/system termination).
## Remediation
### Patches
Users should update to the following versions or later:
- iOS 26.5 / iPadOS 26.5
- iOS 18.7.9 / iPadOS 18.7.9
- iPadOS 17.7.11
- iOS 16.7.16 / iPadOS 16.7.16
- iOS 15.8.8 / iPadOS 15.8.8
- macOS Tahoe 26.5 / macOS Sequoia 15.7.7 / macOS Sonoma 14.8.7
- tvOS 26.5 / watchOS 26.5 / visionOS 26.5
### Workarounds
- Run all software as a non-privileged user (standard user) to diminish the impact of successful exploitation.
- Avoid opening suspicious images or media files from untrusted sources.
## Detection
- **Indicators of Compromise:** Unexpected system reboots (kernel panics), unauthorized new user accounts, or unusual process activity.
- **Detection methods:** Use MDM (Mobile Device Management) solutions to audit OS versions across the enterprise fleet. Monitor for unauthorized installation of unsigned applications.
