EUVD-2025-204025

Comprehensive Technical Analysis of EUVD-2025-204025

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability involves memory corruption when a corrupted ELF (Executable and Linkable Format) image with an oversized file size is read into a buffer without proper authentication. This can lead to unauthorized access to sensitive information and potential system compromise.

Severity Evaluation:

• Base Score: 9.0 (Critical)
• Base Score Version: CVSS 3.1
• Base Score Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N

The CVSS score of 9.0 indicates a critical vulnerability. The key metrics are:

• Attack Vector (AV): Local (L)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Changed (C)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): None (N)

This vulnerability is particularly severe due to its low attack complexity and the high impact on confidentiality and integrity.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Local Exploitation: An attacker with local access to the system can exploit this vulnerability by crafting a malicious ELF image with an oversized file size.
• Supply Chain Attack: An attacker could introduce a corrupted ELF image through compromised software updates or third-party libraries.

Exploitation Methods:

• Buffer Overflow: By reading an oversized ELF image into a buffer, an attacker can cause a buffer overflow, leading to memory corruption.
• Code Execution: The memory corruption could potentially allow for arbitrary code execution, enabling the attacker to gain control over the system.

3. Affected Systems and Software Versions

Affected Products:

• Snapdragon product line, including various versions such as QCA6696, QCA6698AQ, QCA6595, QAM8650P, SA8620P, SRV1H, SA7775P, SA8255P, SA8770P, SA8650P, SA9000P, QCA6595AU, QAMSRV1M, QAMSRV1H, SA8775P, QAM8255P, SRV1M, QAM8620P, SA7255P, QCA6678AQ, QAM8775P, SRV1L, QCA6797AQ.
