CVE-2026-0111

Comprehensive Technical Analysis of CVE-2026-0111

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2026-0111 CVSS Score: 9.8

The vulnerability described in CVE-2026-0111 involves an out-of-bounds write in the ns_GetUserData function within ns_SmscbUtilities.c. This issue arises due to an incorrect bounds check, which can lead to remote escalation of privilege without requiring additional execution privileges or user interaction.

Severity Evaluation:

• CVSS Score: 9.8 (Critical)
• Impact: High
• Exploitability: High

The high CVSS score indicates a critical vulnerability that poses significant risk. The lack of user interaction required for exploitation and the potential for remote escalation of privilege make this vulnerability particularly dangerous.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: An attacker could exploit this vulnerability over a network without needing physical access to the device.
• Privilege Escalation: Once exploited, the attacker could gain elevated privileges on the affected system, potentially leading to full system compromise.

Exploitation Methods:

• Crafted Input: An attacker could send specially crafted input to the ns_GetUserData function, causing an out-of-bounds write.
• Memory Corruption: The out-of-bounds write could corrupt memory, leading to arbitrary code execution or other unintended behaviors.

3. Affected Systems and Software Versions

Affected Systems:

• Android devices, particularly those running versions that include the vulnerable ns_SmscbUtilities.c file.

Software Versions:

• Specific versions of Android and related software components that include the ns_SmscbUtilities.c file with the vulnerable ns_GetUserData function.
