CVE-2025-43336
📋 TL;DR
A macOS permissions vulnerability allows applications with root privileges to access private information they shouldn't normally access. This affects macOS Sequoia, Tahoe, and Sonoma systems before the patched versions. The issue stems from insufficient access restrictions that fail to properly isolate sensitive data from privileged applications.

Worst Case
Malicious root-level applications could access sensitive user data, system files, or other protected information, potentially leading to data theft, privacy violations, or credential compromise.
Likely Case
Legitimate applications with root privileges might inadvertently access protected data, or malware with root access could harvest sensitive information from the system.
If Mitigated
With proper application sandboxing and least-privilege principles, the impact is limited as few applications should have root access, and those that do should be trusted.
🎯 Exploit Status
Requires an attacker to first obtain root privileges through other means, then leverage this vulnerability to access protected data.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: macOS Sequoia 15.7.2, macOS Tahoe 26.1, macOS Sonoma 14.8.2
Vendor Advisory: https://support.apple.com/en-us/125634
Restart Required: Yes
Instructions:
1. Open System Settings 2. Click General 3. Click Software Update 4. Install available updates 5. Restart when prompted
🔧 Temporary Workarounds
Restrict root access
allLimit which applications can run with root privileges and implement strict application allowlisting
Enable full disk encryption
allFileVault encryption provides additional protection for sensitive data at rest
sudo fdesetup enable
🧯 If You Can't Patch
- Implement strict application control policies to prevent unauthorized applications from obtaining root privileges
- Monitor for unusual root-level application activity and implement enhanced logging for privileged operations
