CVE-2025-24195

Comprehensive Technical Analysis of CVE-2025-24195

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-24195 CVSS Score: 9.8

The vulnerability in question is an integer overflow issue in macOS, which has been addressed with improved input validation. The CVSS score of 9.8 indicates a critical severity level. This high score is likely due to the potential for privilege escalation, which can lead to significant security risks.

Severity Evaluation:

• Exploitability: High. Integer overflow vulnerabilities are often exploitable if an attacker can manipulate input data to cause an overflow condition.
• Impact: Critical. Privilege escalation can allow an attacker to gain higher-level access, potentially leading to full system compromise.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Local Exploitation: An attacker with local access to the system could exploit this vulnerability to elevate their privileges.
• Remote Exploitation: If the vulnerable component processes untrusted input from remote sources, an attacker could potentially exploit this vulnerability remotely.

Exploitation Methods:

• Crafted Input: An attacker could craft specific input data designed to trigger the integer overflow.
• Buffer Overflow: The integer overflow could lead to a buffer overflow, allowing the attacker to execute arbitrary code with elevated privileges.

3. Affected Systems and Software Versions

Affected Systems:

• macOS Ventura versions prior to 13.7.5
• macOS Sequoia versions prior to 15.4
• macOS Sonoma versions prior to 14.7.5

Software Versions:

• The vulnerability is fixed in macOS Ventura 13.7.5, macOS Sequoia 15.4, and macOS Sonoma 14.7.5.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patch Management: Ensure that all affected systems are updated to the latest versions where the vulnerability has been addressed (macOS Ventura 13.7.5, macOS Sequoia 15.4, macOS Sonoma 14.7.5).
• Input Validation: Implement additional input validation checks to prevent integer overflow conditions.

Long-Term Strategies:

• Regular Updates: Maintain a regular update schedule for all systems to ensure they are protected against known vulnerabilities.
• Security Audits: Conduct regular security audits to identify and mitigate potential vulnerabilities.
• User Education: Educate users about the risks of privilege escalation and the importance of keeping systems updated.

5. Impact on Cybersecurity Landscape

Broader Implications:

• System Integrity: Privilege escalation vulnerabilities can compromise the integrity of the entire system, leading to data breaches, unauthorized access, and other security incidents.
• Trust and Reputation: Organizations relying on macOS for critical operations may face trust and reputation issues if this vulnerability is exploited.
• Compliance: Failure to address such vulnerabilities can result in non-compliance with regulatory requirements, leading to legal and financial repercussions.

6. Technical Details for Security Professionals

Vulnerability Details:

• Integer Overflow: This type of vulnerability occurs when an arithmetic operation attempts to create a numeric value that is outside the range that can be represented within a given data type.
• Input Validation: The fix involves improved input validation to ensure that all inputs are within acceptable ranges, preventing the overflow condition.

Detection and Response:

• Monitoring: Implement monitoring tools to detect unusual privilege escalation activities.
• Incident Response: Develop an incident response plan that includes steps for identifying, containing, and remediating privilege escalation incidents.
