Vulnerability Details
The official description of this vulnerability states that it allows physical attackers to bypass Carrier Relock due to improper input validation in data related to network restrictions. This vulnerability affects Samsung Android devices running versions prior to the SMR Jan-2026 Release 1.
The CVSS score of 5.2 indicates a medium severity level, primarily due to its potential impact on the integrity and availability of the affected systems. Specifically, the integrity impact is categorized as high, while the availability impact is also high. This vulnerability can be exploited without requiring any privileges or user interaction.
Technical Analysis
The root cause of CVE-2026-20974 is improper input validation, which can allow attackers to manipulate data related to network restrictions. 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 there are no special conditions required for exploitation. Additionally, no privileges are necessary to execute the attack, and user interaction is not required. The confidentiality impact is none, while the integrity and availability impacts are high, indicating significant risk to the device's operation.
Risk & Impact Analysis
The real-world risk associated with CVE-2026-20974 is notable, particularly for organizations that manage devices with Samsung Android systems. Given the nature of the vulnerability, physical access to devices can lead to unauthorized control, which can have serious implications for data security.
Organizations should also consider the potential blast radius of this vulnerability. If an attacker were to exploit it successfully, they could gain access to sensitive information or manipulate device settings, leading to further attacks or data breaches. Therefore, organizations must prioritize patching this vulnerability.
