CVE-2026-0710 (GCVE-0-2026-0710)
Vulnerability from cvelistv5 – Published: 2026-01-23 03:47 – Updated: 2026-01-23 19:04
VLAI
Title
Sipp/sipp: sipp: denial of service and potential arbitrary code execution vulnerability
Summary
A flaw was found in SIPp. A remote attacker could exploit this by sending specially crafted Session Initiation Protocol (SIP) messages during an active call. This vulnerability, a NULL pointer dereference, can cause the application to crash, leading to a denial of service. Under specific conditions, it may also allow an attacker to execute unauthorized code, compromising the system's integrity and availability.

Mitigation ID: MIT-56
Phase: Implementation
Description:
- For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Phase: Requirements
Description:
- Select a programming language that is not susceptible to these issues.
Mitigation
Phase: Implementation
Description:
- Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Phase: Architecture and Design
Description:
- Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Phase: Implementation
Description:
- Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
