CVE-2024-49730 is a vulnerability identified in the FuseDaemon.cpp component of Google Android operating system versions 13 and 14. The root cause is an out-of-bounds write, a type of memory corruption where data is written outside the allocated buffer boundaries. This flaw can be exploited locally by an attacker with limited privileges to escalate their access rights on the device without requiring additional execution privileges or user interaction. The vulnerability falls under CWE-787, indicating improper memory handling that can lead to serious security consequences. The out-of-bounds write can corrupt memory structures, potentially allowing an attacker to execute arbitrary code with elevated privileges or cause denial of service by crashing system components. The CVSS v3.1 base score of 7.8 reflects a high severity due to the vulnerability's impact on confidentiality, integrity, and availability, combined with relatively low attack complexity and no need for user interaction. Although no known exploits are currently reported in the wild, the vulnerability's characteristics make it a significant threat once weaponized. The lack of available patches at the time of reporting necessitates prompt attention from device manufacturers and users. This vulnerability affects a broad range of Android devices running versions 13 and 14, which are widely deployed globally, especially on flagship and recent mobile devices.

The potential impact of CVE-2024-49730 is substantial for organizations and individuals using Android 13 and 14 devices. Successful exploitation allows a local attacker to escalate privileges, potentially gaining full control over the device. This can lead to unauthorized access to sensitive data, installation of persistent malware, disruption of device functionality, and bypass of security controls. For enterprises, compromised devices can serve as entry points into corporate networks, risking data breaches and lateral movement. The vulnerability affects confidentiality by exposing private information, integrity by allowing unauthorized modifications, and availability by enabling denial-of-service conditions. Given the widespread use of Android devices in both consumer and enterprise environments, the scope of affected systems is large. The ease of exploitation without user interaction increases the threat level, especially in scenarios where devices are shared or physically accessible by malicious actors. Although no exploits are currently known in the wild, the vulnerability's characteristics suggest it could be targeted by attackers seeking to gain elevated privileges on Android devices.

To mitigate CVE-2024-49730, organizations and users should prioritize the following actions: 1) Monitor official Google and device manufacturer channels for security patches addressing this vulnerability and apply them promptly once available. 2) Implement strict device access controls to limit local access to trusted users only, reducing the risk of local exploitation. 3) Employ mobile device management (MDM) solutions to enforce security policies, including restricting installation of untrusted applications and controlling device features. 4) Conduct regular security audits and vulnerability assessments on Android devices within the organization to identify and remediate potential weaknesses. 5) Educate users about the risks of physical device access by unauthorized individuals and encourage secure device handling practices. 6) Consider deploying endpoint detection and response (EDR) tools capable of identifying suspicious local privilege escalation attempts on mobile devices. 7) For high-security environments, evaluate the use of hardware-backed security features and sandboxing to limit the impact of potential exploits. These measures, combined with timely patching, will significantly reduce the risk posed by this vulnerability.
