CVE-2025-20899 is a medium-severity vulnerability in Samsung's PushNotification component, identified for multiple Android versions. This vulnerability allows local attackers to access sensitive information, which poses a significant risk to user privacy and data integrity. Organizations utilizing affected versions should act promptly to address the issue.
With a CVSS score of 4.0, this vulnerability indicates a medium level of risk. The potential for exploitation is concerning as attackers may leverage this flaw to gain unauthorized access to private data. The urgency for defenders to remediate this vulnerability is underscored by its classification and the implications of unauthorized access.
The vulnerability was published on February 4, 2025, and is currently marked as deferred. Organizations should monitor updates from Samsung and prioritize patching this vulnerability when a fix becomes available.
Defenders are advised to assess their systems for affected versions of PushNotification to prevent potential data breaches stemming from this vulnerability.
Vulnerability Details
The official CVE description details that improper access control in PushNotification prior to version 13.0.00.15 in Android 12, 14.0.00.7 in Android 13, and 15.1.00.5 in Android 14 allows local attackers to access sensitive information. This vulnerability represents a risk to confidentiality, as sensitive data may be exposed to unauthorized users.
The vulnerability's CVSS score of 4.0, categorized as medium severity, indicates that while the risk is not critical, it should not be overlooked. The attack vector is local, with low complexity, meaning that an attacker does not require elevated privileges or user interaction to exploit this vulnerability. The potential impact on confidentiality is classified as low, while integrity and availability impacts are deemed nonexistent.
Technical Analysis
The root cause of this vulnerability is tied to improper access controls, which fail to restrict access to sensitive information within the PushNotification component. The attack vector being local signifies that the attacker must have physical access to the device, which can reduce the blast radius but still poses a risk in environments where physical security cannot be ensured.
The attack complexity is low, allowing for easier exploitation by a malicious actor. Privileges required are none, indicating that any local user could potentially exploit this flaw without any special permissions or elevated access. User interaction is also not required, further enhancing the risk profile.
The impact on confidentiality is classified as low, which suggests that while sensitive information may be accessible, the scope of data affected may be limited. No integrity or availability impacts have been reported, meaning that there are no concerns regarding data alteration or service disruption.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive information, which could lead to privacy violations and data breaches. The local attack vector may limit the potential for widespread exploitation; however, the risk still exists, particularly in scenarios where devices are not adequately secured.
Organizations should prioritize patching immediately, as the implications of this vulnerability could lead to significant reputational and financial damage should a breach occur. The medium severity rating indicates that while immediate action may not be necessary, timely remediation is crucial to maintain security posture.

Affected Versions
Affected versions include PushNotification prior to version 13.0.00.15 in Android 12, 14.0.00.7 in Android 13, and 15.1.00.5 in Android 14. If specific version information is not known, all versions prior to vendor patch should be considered affected.
Mitigation & Remediation
Organizations should prioritize patching immediately. Update to the latest versions of PushNotification as soon as they are available to mitigate this vulnerability. If a patch is unavailable, consider implementing configuration hardening measures to restrict access to sensitive information.
Monitoring for unauthorized access attempts can also help in identifying potential exploitations of this vulnerability while waiting for an official patch. Organizations should consider utilizing penetration testing services to assess their current security posture and identify any potential weaknesses.
Detection Guidance
To detect potential exploitation, organizations should monitor logs for abnormal access patterns, particularly focusing on unauthorized access attempts to sensitive information. Behavioral anomalies may indicate attempts to exploit this vulnerability, thereby necessitating immediate investigation.
Network signatures related to unauthorized access attempts should also be established to enhance detection capabilities. Regular reviews of system changes can help identify potential indicators of compromise.
