Overview<\/strong><\/p>\n

The cybersecurity world is rife with complex challenges, and the recent discovery of a severe vulnerability in Samsung’s line of mobile and wearable processors adds another dimension to this complexity. This vulnerability, designated as CVE-2025-47202, affects a broad range of Samsung’s processors, including its mobile, wearable, and modem processors. With a CVSS severity score of 9.1, it poses a significant risk to the integrity, confidentiality, and availability of the systems<\/a> that it affects.
\nThis vulnerability is particularly concerning because of its potential<\/a> impact. If successfully exploited, it could lead to a complete system<\/a> compromise or data leakage. Given the widespread use of Samsung’s processors in various devices globally, this vulnerability requires immediate attention and remediation from both Samsung<\/a> and the users of its processors.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-47202
\nSeverity: Critical (9.1 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise and data<\/a> leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Samsung Mobile Processor<\/a> | Exynos 980, 990, 850, 1080, 2100, 1280, 2200, 1330, 1380, 1480, 2400, 1580
\nSamsung Wearable Processor<\/a> | 9110, W920, W930, W1000
\nSamsung Modem | 5123, 5300, 5400<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability lies in the Radio Resource Control<\/a> (RRC) of the affected Samsung processors. The RRC lacks a length check mechanism, which can lead to out-of-bounds writes<\/a>. An attacker could exploit this vulnerability by sending specially crafted data to the target system<\/a>. Because of the absence of a length check, the system would write this data beyond the intended boundary, potentially overwriting other important data or code and leading to unexpected behavior, including a system crash or unauthorized code<\/a> execution.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here is a conceptual example of how an attacker might exploit<\/a> this vulnerability:<\/p>\n

POST \/RRC\/endpoint HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/octet-stream\n{ \"payload\": \"AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA...\" }<\/code><\/pre>\n
In this example, the attacker sends a large amount of data (‘A’) to the RRC endpoint. The target system, lacking a length check mechanism, attempts to write all of this data in a location that cannot accommodate it, leading to an out-of-bounds write and potential system<\/a> compromise.<\/p>\n","protected":false},"excerpt":{"rendered":"
