Summary
by MITRE • 03/10/2026
In ns_GetUserData of ns_SmscbUtilities.c, there is a possible out of bounds write due to an incorrect bounds check. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

The vulnerability identified as CVE-2026-0113 resides within the ns_GetUserData function of the ns_SmscbUtilities.c file, representing a critical out-of-bounds write flaw that fundamentally compromises system integrity. This issue manifests from an inadequate bounds checking mechanism that fails to properly validate array access limits, creating a scenario where malicious data can overwrite adjacent memory locations beyond the intended buffer boundaries. The flaw exists within the SMS cell broadcast utilities component of the affected software stack, which handles telecommunications messaging protocols and related data processing functions.
The technical implementation of this vulnerability stems from a classic programming error where the bounds validation logic contains a logical flaw that allows an attacker to manipulate input parameters to bypass legitimate size checks. When the ns_GetUserData function processes incoming SMS cell broadcast data, it performs calculations to determine buffer allocation and data placement, but the boundary verification mechanism contains a flaw that permits memory corruption. This type of vulnerability aligns with CWE-129, which specifically addresses insufficient bounds checking, and represents a direct pathway for privilege escalation attacks.
The operational impact of this vulnerability extends beyond simple memory corruption, as it enables remote privilege escalation without requiring any additional execution privileges or user interaction. This characteristic makes the flaw particularly dangerous since it can be exploited entirely through network-based attacks against vulnerable systems. The absence of user interaction requirements means that attackers can initiate exploitation autonomously, potentially compromising entire telecommunications infrastructure or connected systems. The remote nature of the attack vector allows for widespread impact across multiple devices and networks that utilize the vulnerable software components.
Security implications of CVE-2026-0113 align with ATT&CK technique T1068, which covers 'Exploitation for Privilege Escalation', and T1190, covering 'Exploit Public-Facing Application'. The vulnerability creates a pathway for attackers to gain elevated system privileges, potentially enabling them to execute arbitrary code with administrative rights, access sensitive data, or establish persistent access points within target networks. The exploitability is further enhanced by the lack of user interaction requirements, which eliminates the need for social engineering or targeted phishing attacks that typically complicate exploitation efforts.
Mitigation strategies for this vulnerability should focus on immediate code-level fixes including proper bounds checking implementations, input validation enhancements, and comprehensive code reviews targeting similar patterns within the software stack. Organizations should implement network segmentation to limit exposure of vulnerable systems, deploy intrusion detection systems to monitor for exploitation attempts, and establish robust patch management protocols to ensure timely remediation. Additionally, the implementation of address space layout randomization and other exploit mitigation techniques can help reduce the effectiveness of potential exploitation attempts. Regular security assessments and vulnerability scanning should be conducted to identify similar issues within the broader codebase, particularly focusing on memory management patterns and buffer handling routines that may contain analogous flaws.
