Understanding and Mitigating CVE-2024-34724: Elevation of Privilege Vulnerability in Android

The recent publication of CVE-2024-34724 highlights a significant vulnerability affecting the Android System on Chip (SoC), identified as an elevation of privilege due to a race condition in the kernel. This vulnerability, reported by Google Android, has a high CVSS score of 7.0, indicating its potential impact. This article provides an in-depth analysis of the vulnerability and effective mitigation strategies.

Overview of CVE-2024-34724

CVE-2024-34724 involves an elevation of privilege caused by a race condition in the _UnrefAndMaybeDestroy function within the pmr.c file. This vulnerability allows for potential arbitrary code execution at the kernel level, leading to local escalation of privilege without requiring additional execution privileges or user interaction. The issue primarily affects devices with Android SoC, and the associated product identified is the PowerVR GPU from Imagination Technologies.

Key details include:

• Vendor: Google
• Product: Android SoC
• Severity: High
• Attack Vector: Local
• Privileged Required: Low

Impact and Risks

This vulnerability's scope is unchanged, meaning any successful exploitation could lead to an attacker gaining complete control over a device's kernel. The potential impacts are:

• Confidentiality Impact: High
• Integrity Impact: High
• Availability Impact: High

The risk is further exacerbated as the attack complexity is only moderate, and no user interaction is required for exploitation. Thus, devices with the affected Android SoC and PowerVR GPU are at considerable risk if not promptly mitigated.

Mitigation and Protection Strategies

Mitigating CVE-2024-34724 involves several strategic actions to ensure the affected systems are protected against potential exploits.

• Apply Security Updates: Regularly update the Android operating system and apply any patches released by Google and Imagination Technologies related to this CVE. Prompt installation of security patches is crucial to mitigate the exposure to this vulnerability.
• Monitor Vulnerability Announcements: Stay vigilant by monitoring official channels such as the Android security bulletin. This ensures you are aware of the latest developments and provided fixes.
• Implement Security Controls: Employ security controls such as endpoint protection, intrusion detection systems (IDS), and mobile device management (MDM) solutions to detect and prevent potential exploitation attempts.
• Security Best Practices: Follow best practices for Android security, including limiting the permissions required for applications, avoiding installation of software from untrusted sources, and educating users about security hygiene.

To further mitigate risks, organizations should consider conducting regular security assessments and employing advanced threat detection solutions that can help in identifying and neutralizing attempts to exploit the vulnerability.

Conclusion

The discovery of CVE-2024-34724 underlines the importance of rigorous security practices and prompt mitigation strategies to protect against significant vulnerabilities. By applying the recommended updates, monitoring official advisories, and implementing robust security controls, the risks associated with this elevation of privilege vulnerability can be effectively mitigated.
