Overview
In the realm of cybersecurity, a newly discovered vulnerability, CVE-2025-23102, poses substantial risks to a range of Samsung Mobile Processors. This vulnerability, found in Exynos 980, 990, 1080, 2100, 1280, 2200, 1380, 1480 and 2400 models, may lead to a potential system compromise or data leakage. It is a significant concern for all users and organizations employing the affected processors, as an attacker exploiting this security flaw could escalate privileges, potentially gaining unauthorized access to sensitive data.
Vulnerability Summary
CVE ID: CVE-2025-23102
Severity: High (CVSS: 8.8)

Privileges Required: Low
User Interaction: Required
Impact: Privilege Escalation, Potential System Compromise or Data Leakage
Affected Products
Product | Affected Versions
Samsung Mobile Processor Exynos | 980, 990, 1080, 2100, 1280, 2200, 1380, 1480, 2400
How the Exploit Works
The vulnerability, a Double Free error, occurs when an application releases a specific memory area twice. This could lead to memory corruption, allowing an attacker with local access to the device to exploit this flaw. By triggering the Double Free error, an attacker could potentially alter the application’s flow, enabling them to execute arbitrary code or escalate privileges, leading to unauthorized access to the system and sensitive data.
Conceptual Example Code
The following pseudocode illustrates a conceptual example of how the Double Free vulnerability might be exploited:
// Allocate memory
pointer = malloc(size);
// Use the memory...
...
// Free the memory
free(pointer);
// Use the pointer again in the code, leading to double free
free(pointer);
// Memory corruption occurs here. An attacker can exploit this to execute arbitrary code or perform privilege escalation
Please note that this is a simplified representation of the exploit. Real-world exploitation would require a deep understanding of memory management and the specific software’s inner workings.
Mitigation
To mitigate this vulnerability, users are advised to apply the patch provided by the vendor, Samsung, as soon as possible. Until the patch can be applied, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) may serve as a temporary mitigation measure. Regularly updating and patching systems can help prevent exploitation of such vulnerabilities.
