CVE-2025-20904 is a medium-severity vulnerability affecting Samsung's Android platform. This vulnerability allows local privileged attackers to cause memory corruption due to an out-of-bounds write in the mPOS TUI trustlet. The CVSS score for this vulnerability is 6.3, indicating a notable risk to systems utilizing the affected software.
The exploitation of this vulnerability can lead to significant impacts on confidentiality and integrity, necessitating a prompt response from affected organizations. The vulnerability affects multiple Samsung Android versions, emphasizing the importance of timely patches and updates.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. The potential for memory corruption presents an avenue for local attacks, which may compromise user data and overall device security.
Given the nature of the vulnerability and its exploitation status, organizations must remain vigilant and ensure they are running updated software versions to protect against potential threats.
Vulnerability Details
The official CVE description states that the out-of-bounds write in mPOS TUI trustlet prior to SMR Feb-2025 Release 1 allows local privileged attackers to cause memory corruption. This vulnerability is classified under CWE-787, which relates to the improper control of a resource through its lifecycle.
The vulnerability has been scored with a CVSS version of 3.1, and while it has a medium severity rating, the actual impact can vary based on the specific implementation and configurations of the affected systems.
Technical Analysis
The root cause of this vulnerability stems from an out-of-bounds write operation, which can occur when the software does not properly validate input sizes. This leads to memory corruption that can potentially be exploited by local attackers.
The attack vector for this vulnerability is local, meaning that an attacker must have local access to the system to exploit it. The attack complexity is rated as low, indicating that the exploit can be executed with minimal effort, provided the attacker has the necessary privileges.
To exploit this vulnerability, high privileges are required, and no user interaction is necessary. The impact on confidentiality and integrity is high, while the availability impact is assessed as low.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-20904 is significant, particularly for organizations using the affected versions of Samsung Android. Attackers may leverage this vulnerability to escalate their privileges and manipulate data or perform unauthorized actions within the system.
The blast radius potential is considerable; if exploited, it could compromise the integrity of sensitive data and lead to broader system vulnerabilities. Organizations must assess their exposure to ensure their defenses are appropriately configured and patched.
Given that the CVSS score indicates a medium severity, organizations should address this vulnerability in their priority patch cycle to mitigate potential risks effectively.
