CVE-2026-20979 is a high-severity vulnerability affecting Samsung Android devices, specifically related to improper privilege management in the device's Settings. This vulnerability allows local attackers to launch arbitrary activities with Settings privileges, which poses a significant risk to device security and user data integrity. With a CVSS score of 8.4, it falls into the high severity category, indicating a serious concern that organizations must address promptly.
The potential impact of this vulnerability is considerable, as it could enable attackers to exploit weak privilege management and execute unauthorized actions on affected devices. Given the increasing reliance on mobile devices for sensitive activities, the urgency for organizations to patch this vulnerability cannot be overstated. Organizations should prioritize patching immediately to mitigate the associated risks.
Currently, there are no known public exploits available for CVE-2026-20979, and it has not been included in any Known Exploited Vulnerabilities (KEV) catalogs. Despite the absence of active exploitation reports, the characteristics of this vulnerability suggest it could be leveraged by local attackers, making it essential for organizations to remain vigilant.
Samsung has released patches addressing this vulnerability in the SMR Feb-2026 Release 1. Organizations using affected Samsung Android devices should schedule remediation as part of their security management protocols.
Vulnerability Details
The CVE-2026-20979 vulnerability is characterized by improper privilege management in the Settings application of Samsung Android systems prior to the SMR Feb-2026 Release 1. The vulnerability allows local attackers to launch arbitrary activities with elevated Settings privileges.
The CVSS 4.0 score of 8.4 reflects a high severity level, indicating a significant impact on confidentiality and integrity, while availability is rated low. The attack vector is classified as local, with low complexity and low privileges required for exploitation.
The vulnerability was published on February 4, 2026, and affects various Samsung Android versions, including 15.0 and 16.0 across multiple security maintenance releases.
Technical Analysis
The root cause of CVE-2026-20979 stems from improper privilege management, which fails to sufficiently restrict unauthorized access to the Settings application. This weakness allows local attackers to exploit the system and perform actions beyond their intended privileges.
The attack vector for this vulnerability is local, meaning that an attacker would need physical access to the device to exploit it. The attack complexity is low, and no user interaction is required to trigger the vulnerability. The required privileges are also low, making it easier for attackers to execute unauthorized actions.
In terms of impact, the vulnerability poses high risks to confidentiality and integrity, as attackers can manipulate Settings features that control critical device functions. However, availability impacts are rated low, indicating that the exploitation does not necessarily lead to denial of service.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive settings and configurations, which can lead to broader security incidents. The blast radius is significant as mobile devices often have access to sensitive data and applications, making them attractive targets for exploitation.
Given the high CVSS score and the nature of the vulnerability, organizations should assess their exposure and prioritize remediation efforts. The lack of active exploitation reports does not diminish the risk presented by this vulnerability, making it essential to address it in a timely manner.
The urgency for addressing CVE-2026-20979 is high, and organizations should schedule remediation as part of their immediate security actions. Implementing necessary patches will help mitigate risks and enhance overall device security.
