CVE-2025-20885 is a medium-severity vulnerability affecting Samsung Android devices that allows local privileged attackers to exploit an out-of-bounds write condition within the softsim trustlet. This flaw has been classified under the Common Weakness Enumeration (CWE) identifier CWE-787, indicating a potential risk of memory corruption. The CVSS score for this vulnerability is 6.4, highlighting the need for organizations to take immediate action.
Risk to organizations includes unauthorized access to sensitive data and potential system instability. Due to the nature of this vulnerability, local access is required, which may limit its overall exposure. However, the impact can still be significant, especially in environments where sensitive information is processed.
The vulnerability was published on February 4, 2025, indicating that organizations should assess their risk exposure and urgency for remediation. Given the medium severity, organizations should address this vulnerability in their priority patch cycle.
As for the exploitation status, there are currently no known exploits or proof-of-concept (PoC) code available for this vulnerability. Organizations should remain vigilant and continuously monitor threat intelligence for updates.
Vulnerability Details
The official description of CVE-2025-20885 states: 'Out-of-bounds write in softsim trustlet prior to SMR Jan-2025 Release 1 allows local privileged attackers to cause memory corruption.' This vulnerability is categorized as a privilege escalation issue, as it requires high privileges to exploit.
The CVSS score for this vulnerability varies slightly between different sources, with a base score of 6.4 from Samsung and 6.7 from NVD. This reflects the potential for significant impacts on confidentiality, integrity, and availability, all classified as high impact.
The vulnerability affects several versions of Samsung Android, specifically those prior to the SMR Jan-2025 Release 1. Organizations should refer to the detailed configuration information to assess their exposure.
Technical Analysis
The root cause of CVE-2025-20885 is an out-of-bounds write in the softsim trustlet, which occurs when memory access goes beyond the boundaries allocated for program execution. This vulnerability has a local attack vector requiring high privileges and presents a high attack complexity due to the necessary conditions for exploitation.
The attack does not require user interaction, making it easier for an attacker with local access to exploit this vulnerability. The potential impacts include high confidentiality, integrity, and availability risks, which can severely affect the system's overall functionality.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-20885 is significant, especially in environments that rely on Samsung Android devices for critical operations. The blast radius for this vulnerability could extend to various applications and services that utilize the affected trustlet, potentially leading to unauthorized data access and system instability.
Organizations should prioritize patching immediately. With the CVSS score indicating a medium severity, timely remediation is crucial to prevent exploitation. Continuous monitoring and implementing robust security measures can help mitigate the risks posed by this vulnerability.
