CVE-2025-20905 is classified as a medium-severity vulnerability affecting Samsung's Android platform. This vulnerability allows local privileged attackers to perform out-of-bounds reads and writes in the mPOS TUI trustlet prior to the SMR Feb-2025 Release 1. The potential impact includes unauthorized access to sensitive memory regions, which could lead to data leakage or corruption.
The CVSS score for this vulnerability is 6.3, indicating a medium severity level. Its significance lies in the fact that it impacts confidentiality and integrity, both rated high, while availability is rated low. The attackers require high privileges but do not need user interaction, making it easier for them to exploit this vulnerability in a local context.
Organizations using affected Samsung Android versions should be aware of the urgency to address this vulnerability. Given the potential for local privileged attackers to exploit this flaw, immediate actions are necessary to mitigate risks.
The vulnerability was published on February 4, 2025, and has been analyzed by Samsung Mobile Security. As of now, there are no public exploits confirmed, but the threat landscape should always be monitored closely.
Vulnerability Details
The official description of CVE-2025-20905 states that it involves an out-of-bounds read and write in the mPOS TUI trustlet prior to the SMR Feb-2025 Release 1. This condition allows local privileged attackers to read and write out-of-bounds memory, which can lead to unauthorized access to sensitive data.
The CVSS score of 6.3 indicates a medium severity, with a vector string of CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:L. This score reflects the ease of exploitation and the potential impact on confidentiality and integrity.
The affected product is Samsung's Android operating system, particularly versions prior to the SMR February 2025 Release 1. The vulnerability was made public on February 4, 2025, and is classified under CWE-125.
Technical Analysis
The root cause of this vulnerability lies in improper memory management within the mPOS TUI trustlet. Attackers can exploit the out-of-bounds read and write conditions to access or modify memory that should not be accessible to them.
The attack vector for this vulnerability is local, meaning that an attacker must have physical access to the device. The attack complexity is low, and the privileges required are high, indicating that the attacker must already have some level of access to the system.
No user interaction is required for exploitation, which increases the risk associated with this vulnerability. The confidentiality and integrity impacts are rated high, indicating that sensitive information could be compromised or altered, while the availability impact is rated low.
Risk & Impact Analysis
Risk to organizations includes potential data breaches and unauthorized access to sensitive information. The blast radius for this vulnerability can be significant, especially for organizations that utilize mobile payment systems relying on the affected trustlet.
Organizations should prioritize remediation efforts based on the CVSS score of 6.3, which falls into the medium severity category. Security teams should evaluate their exposure to this vulnerability and implement necessary patches or mitigation strategies.
Given the CVSS score and the potential impact, organizations are urged to address this vulnerability in their priority patch cycle.
