CVE-2025-20881 is a high-severity vulnerability affecting Samsung's Android operating system. This vulnerability allows for an out-of-bounds write in accessing the buffer that stores the decoded video frames in libsthmbc.so prior to the SMR Jan-2025 Release 1. Local attackers may exploit this vulnerability to execute arbitrary code with elevated privileges. User interaction is required to trigger this vulnerability, which adds a layer of complexity to potential exploitation.
The CVSS score for this vulnerability is 7.0, categorized as high severity. The attack vector is local, requiring direct access to the vulnerable system, and the attack complexity is considered high. This means that successful exploitation may require a specific environment or user interaction, making it less accessible to general attackers.
Risk to organizations includes unauthorized code execution, which may lead to data breaches or system compromise. Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability.
Currently, there are no public exploits confirmed for this vulnerability, and it is not included in the Known Exploited Vulnerabilities (KEV) catalog. However, the potential impact of an exploit necessitates immediate attention from security teams.
Vulnerability Details
The vulnerability is classified as an out-of-bounds write, a known issue under CWE-787. The affected products include various versions of Samsung's Android operating system, specifically those running versions 12.0 to 14.0 with multiple security releases. The vulnerability was published on February 4, 2025.
Technical Analysis
The root cause of this vulnerability lies in improper memory management, specifically an out-of-bounds write condition that occurs when handling video frame buffers. This can lead to arbitrary code execution if exploited successfully.
The attack vector is local, meaning the attacker must have physical access to the device. The attack complexity is high due to the requirement for user interaction to trigger the vulnerability. Privileges required for exploitation are none, and user interaction is required.
The confidentiality, integrity, and availability impacts of this vulnerability are all rated as high. An attacker could potentially gain full control over the affected device, leading to severe consequences.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-20881 is significant, particularly for organizations that utilize Samsung Android devices in sensitive environments. The potential for arbitrary code execution can lead to unauthorized access, data loss, and operational disruptions.
Organizations must recognize the urgent need for patching due to the high impact this vulnerability poses. It is advisable to schedule immediate remediation efforts to mitigate related risks.
With a CVSS score of 7.0, this vulnerability falls within a high urgency bracket, emphasizing the necessity for organizations to prioritize its resolution. Potential blast radius includes all devices that run the affected Android versions, amplifying the risk across organizational networks.
