CVE-2025-21042 is classified as a high-severity vulnerability with a CVSS score of 8.8. This vulnerability allows remote attackers to execute arbitrary code due to an out-of-bounds write in the libimagecodec.quram.so library prior to the SMR April 2025 Release 1. Given its critical nature, organizations using affected Samsung Android devices are at significant risk.
The exploitation status is confirmed, as there is known exploit activity associated with this vulnerability. Attackers may leverage this vulnerability to gain unauthorized access to systems, making it imperative for organizations to address this issue as a priority.
Organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability. The potential for remote code execution represents a serious threat, and timely action is essential to protect sensitive data and maintain system integrity.
In summary, CVE-2025-21042 poses a significant threat to Samsung Android devices, necessitating urgent remediation efforts to safeguard against potential exploitation.
Vulnerability Details
The official CVE description states: 'Out-of-bounds write in libimagecodec.quram.so prior to SMR Apr-2025 Release 1 allows remote attackers to execute arbitrary code.' This vulnerability falls under CWE-787, indicating issues related to improper control of a resource through its lifetime.
The CVSS score of 8.8 indicates a high severity level, which means organizations must take immediate action. The vulnerability affects Samsung Android products, specifically those operating under version 13.0 and 14.0, as detailed in the configurations.
The vulnerability was published on September 12, 2025, and its implications extend to all devices that have not been patched since then. Organizations must ensure that their systems are updated accordingly.
Technical Analysis
The root cause of CVE-2025-21042 is an out-of-bounds write error in the libimagecodec.quram.so library, which can be exploited over a network. This vulnerability requires low attack complexity, as no special privileges are needed to exploit it, thus increasing its potential for widespread impact.
User interaction is required for exploiting this vulnerability, which means that an attacker may need the target user to perform certain actions that could lead to the execution of arbitrary code. The confidentiality, integrity, and availability impacts are all rated as high, indicating that successful exploitation could lead to significant damage.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive information, potential data breaches, and loss of system integrity. The blast radius is substantial, as a single exploited device could lead to further compromise within an organization's network.
Given the CVSS score of 8.8 and its inclusion in the KEV catalog, organizations must assess their exposure and prioritize remediation efforts. The urgency for patching is critical, especially for devices running vulnerable versions of Samsung Android.
