9.8 CRITICAL

📋 TL;DR

An integer overflow vulnerability in macOS allows local users to elevate privileges by exploiting improper input validation. This affects macOS Ventura, Sequoia, and Sonoma versions before the patched releases. Attackers could gain root access on vulnerable systems.

💻 Affected Systems

Products:
  • macOS
Versions: Versions before macOS Ventura 13.7.5, macOS Sequoia 15.4, macOS Sonoma 14.7.5
Operating Systems: macOS Ventura, macOS Sequoia, macOS Sonoma
Default Config Vulnerable: ⚠️ Yes
Notes: All default configurations of affected macOS versions are vulnerable. The vulnerability requires local access to exploit.

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise with root-level access, enabling installation of persistent malware, data theft, and lateral movement across the network.

🟠

Likely Case

Local privilege escalation allowing attackers to bypass security controls, install unauthorized software, and access sensitive system resources.

🟢

If Mitigated

Limited impact with proper patch management and least privilege principles in place, though still a serious local vulnerability.

🌐 Internet-Facing: LOW - This is a local privilege escalation vulnerability requiring local access to the system.
🏢 Internal Only: HIGH - Internal attackers or compromised accounts can exploit this to gain elevated privileges on macOS workstations and servers.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires local access to the system. Public disclosures suggest proof-of-concept code exists, making weaponization likely.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: macOS Ventura 13.7.5, macOS Sequoia 15.4, macOS Sonoma 14.7.5

Vendor Advisory: https://support.apple.com/en-us/122373

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 local access

all

Limit physical and remote local access to vulnerable systems through access controls and network segmentation

Implement least privilege

all

Ensure users operate with minimal necessary privileges to reduce impact of successful exploitation

🧯 If You Can't Patch

  • Isolate vulnerable systems from critical network segments
  • Implement strict monitoring for privilege escalation attempts and unusual process behavior

🔍 How to Verify

Check if Vulnerable:

Check macOS version in System Settings > General > About. If version is earlier than Ventura 13.7.5, Sequoia 15.4, or Sonoma 14.7.5, system is vulnerable.

Check Version:

sw_vers

Verify Fix Applied:

Verify macOS version shows Ventura 13.7.5, Sequoia 15.4, or Sonoma 14.7.5 or later in System Settings > General > About.

📡 Detection & Monitoring

Log Indicators:

  • Unexpected privilege escalation events in system logs
  • Unusual process creation with elevated privileges
  • Failed authorization attempts followed by successful privileged operations

Network Indicators:

  • Unusual outbound connections from privileged processes
  • Lateral movement attempts from previously low-privilege accounts

SIEM Query:

source="macos_system_logs" AND (event_type="privilege_escalation" OR process_elevation="true")
