CVE-2024-43767 is a high-severity vulnerability affecting Google Android systems. This vulnerability allows for a possible heap overflow due to improper input validation in the function prepare_to_draw_into_mask of SkBlurMaskFilterImpl.cpp. With a CVSS score of 8.8, this vulnerability is classified as high, indicating a significant risk to the integrity and security of affected systems.
Risk to organizations includes potential remote code execution capabilities without requiring additional execution privileges. Notably, this vulnerability does not require user interaction for exploitation, increasing its risk profile. Organizations using affected versions of Google Android should prioritize remediation to mitigate potential threats.
Despite the high exploitability score, there are currently no known public exploits available for this vulnerability. However, it is critical for organizations to remain vigilant and proactive in their security posture, especially considering the implications of remote code execution.
Organizations should prioritize patching immediately to safeguard their systems against potential exploitation of this vulnerability.
Vulnerability Details
The vulnerability is specifically associated with Google Android and is classified under CWE-94 for code injection. The function in question, prepare_to_draw_into_mask, is responsible for handling graphical operations, where improper input validation may lead to a heap overflow.
The vulnerability affects multiple versions of Android, including versions 12.0 through 15.0. It was officially published on January 3, 2025, and has been analyzed by security teams for potential impact.
Technical Analysis
The root cause of CVE-2024-43767 lies in the lack of proper input validation within the SkBlurMaskFilterImpl.cpp file. This oversight enables attackers to exploit the vulnerability via crafted network packets, leading to a heap overflow.
The attack vector is categorized as NETWORK, which means that an attacker can exploit this vulnerability remotely without physical access to the device. The complexity of the attack is low, requiring no privileges and minimal user interaction, making it easily exploitable.
The impacts of this vulnerability are severe, affecting confidentiality, integrity, and availability. A successful exploit could lead to unauthorized access and control of affected devices.
Risk & Impact Analysis
Real-world deployment risk associated with CVE-2024-43767 is significant, particularly for organizations relying on Google Android systems for critical operations. The potential for remote code execution without user interaction increases the blast radius, allowing attackers to compromise multiple devices within an organization.
Organizations should assess their exposure to this vulnerability and take immediate action to implement patches. Given the high CVSS score and the lack of public exploits, proactive measures are essential to mitigate risks.
The urgency of addressing this vulnerability is high, necessitating prioritization in the patching cycle to protect against potential exploitation.
