CVE-2025-20892 is identified as a medium severity vulnerability affecting Samsung's Android operating system. This vulnerability allows physical attackers to execute fastboot commands due to a protection mechanism failure in the bootloader prior to the SMR Jan-2025 Release 1. As an attacker requires physical access and user interaction to trigger the vulnerability, the risk is somewhat mitigated, but organizations should be aware of its potential impact.
With a CVSS score of 5.9, this vulnerability falls into the medium severity category, indicating that while it is not as critical as high-severity vulnerabilities, it still presents significant risks that organizations must address. The combination of high confidentiality and integrity impact makes it essential for security teams to include this in their risk management practices.
Currently, there are no known exploits available for CVE-2025-20892, and it is not included in the Known Exploited Vulnerability (KEV) catalog. However, given that it has been analyzed and disclosed, organizations should prioritize patching this vulnerability to prevent any potential exploitation.
Organizations should address this vulnerability in their priority patch cycle to ensure their systems remain secure from potential attacks. The user interaction requirement does not diminish the need for prompt remediation, as physical access could be obtained by malicious actors.
Vulnerability Details
The vulnerability described by CVE-2025-20892 arises from a failure in the protection mechanism of the bootloader, allowing unauthorized fastboot command execution. The official description indicates the need for user interaction, which means that an attacker must physically access the device and exploit this flaw. The CVSS score of 5.9 indicates a medium severity level, with high confidentiality and integrity impacts, while the availability impact remains none.
The configurations affected include various versions of Samsung Android, specifically those prior to the SMR Jan-2025 Release 1, encompassing both Android 13.0 and Android 14.0 releases. The vulnerability's exploitation could lead to unauthorized access and manipulation of sensitive data, further emphasizing the urgency for remediation.
Technical Analysis
The root cause of CVE-2025-20892 is attributed to a protection mechanism failure within the bootloader. The attack vector is physical, meaning that an attacker must have direct access to the device to exploit this vulnerability. The attack complexity is low, as it does not require specialized skills beyond the ability to interact with the device.
No privileges are required, and user interaction is necessary to trigger the vulnerability. The high confidentiality and integrity impacts suggest that successful exploitation could lead to unauthorized exposure or alteration of sensitive information, while the availability impact remains unaffected.
Risk & Impact Analysis
The risk to organizations includes potential unauthorized access to sensitive data, leading to data breaches or manipulation. Given the nature of the vulnerability, which requires physical access and user interaction, the immediate risk may be considered lower than vulnerabilities that can be exploited remotely. However, organizations should still be vigilant, as physical access can be obtained through various means.
The urgency for organizations to address this vulnerability is categorized as high, as it can lead to significant data integrity and confidentiality issues. Organizations should implement patches promptly to mitigate risks and ensure that their systems are protected against potential physical attacks.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |

Affected Versions
The affected versions include multiple releases of Samsung's Android, specifically versions 13.0 and 14.0 prior to the SMR Jan-2025 Release 1. Organizations should ensure that they are running the latest secure versions to mitigate risks associated with this vulnerability.
Mitigation & Remediation
To address this vulnerability, organizations should prioritize applying the latest security patches provided by Samsung. Updating to the SMR Jan-2025 Release 1 or later will resolve this issue. If immediate patching is not feasible, organizations should implement physical security measures to restrict unauthorized access to devices.
In addition, practices such as regular security assessments and monitoring can help organizations identify potential vulnerabilities proactively. For comprehensive security, organizations should consider engaging in penetration testing to validate the effectiveness of their security controls.
Detection Guidance
Organizations should monitor logs for any unauthorized physical access attempts to their devices. Behavioral anomalies during boot processes may indicate an attempt to exploit this vulnerability. Additionally, system changes during bootloader interactions should be scrutinized for potential unauthorized commands.
