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

A critical vulnerability labeled as CVE-2025-26783 has been identified in several Samsung processors. These include the Mobile Processor, Wearable Processor, and Modem Exynos with various model numbers. The vulnerability, due to incorrect handling of undefined values, can potentially lead to a Denial of Service (DoS), compromising system integrity and leading to potential data leakage.<\/p>\n

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

CVE ID: CVE-2025-26783
\nSeverity: High (7.5 CVSS score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Successful exploitation of this vulnerability could lead to a Denial of Service (DoS), system compromise, and potential data leakage.<\/p>\n

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

Product | Affected Versions<\/p>\n

Samsung Mobile Processor Exynos | 2100, 1280, 2200, 1330, 1380, 1480, 2400
\nSamsung Wearable Processor | W1000
\nSamsung Modem | 5300, 5400<\/p>\n

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

The vulnerability arises from the incorrect handling of undefined values in the Real-time Radio Controller (RRC) of the affected processors. This mishandling can trigger a Denial of Service (DoS) condition, disrupting the normal functioning of the device. Depending upon the context and the attacker’s objectives, this could potentially lead to a full system compromise or even data leakage.<\/p>\n

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

While a specific exploit code is not available, an attacker could potentially craft a malicious payload that takes advantage of the mishandling of undefined values. A conceptual example could look similar to this pseudocode:<\/p>\n

POST \/rrc\/handler HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"undefined_value\": \"trigger_DoS\" }<\/code><\/pre>\n
This conceptual example showcases a payload designed to exploit the vulnerability by sending an undefined value to the RRC handler, triggering a Denial of Service condition.
\nPlease note this is a conceptual example and the actual exploit might be different based on the specific APIs and system architecture of the affected products.<\/p>\n","protected":false},"excerpt":{"rendered":"
