CVE-2026-101290 in Safetyscanners Base CPP Driver
Summary
by MITRE • 10/15/2026
A remote attacker may send a specially crafted network packet that causes the affected application to perform an out-of-bounds memory read due to insufficient validation of packet length. This may result in an application crash and a denial-of-service condition.

The vulnerability described constitutes a classic input validation failure, specifically categorized under CWE-125: Out-of-Bounds Read. In this scenario, the affected application fails to adequately verify the integrity of incoming network packets before processing their contents. The core technical flaw lies in the absence or insufficiency of boundary checks regarding packet length fields. When an attacker transmits a specially crafted packet with malformed length indicators, the application's parsing logic proceeds under the assumption that the data is valid and contained within expected memory limits. Consequently, the software attempts to read from memory addresses beyond the allocated buffer boundaries, leading to an out-of-bounds access event. This type of error typically occurs during the deserialization or parsing phase where raw byte streams are converted into structured objects without rigorous sanity checks on size constraints relative to available heap or stack space.
From a security operations perspective, this vulnerability is primarily exploitable for denial-of-service attacks rather than remote code execution in its current manifestation. The immediate operational impact of an out-of-bounds read is often the corruption of memory state or the triggering of hardware-level exceptions such as segmentation faults. These events cause the application process to terminate abruptly, resulting in a service disruption for legitimate users. While some implementations might leak sensitive information through side channels if the read data includes confidential structures, the primary risk highlighted here is system instability and availability loss. Attackers can automate this behavior by sending multiple malformed packets at high frequencies, effectively exhausting server resources or crashing critical services repeatedly to achieve sustained denial of service conditions.
This vulnerability aligns with MITRE ATT&CK technique T1498: Network Denial of Service, specifically the sub-technique involving resource exhaustion through application crashes. The attack vector is remote and requires no authentication if the affected port is exposed to untrusted networks. To mitigate this risk, developers must implement strict input validation mechanisms that enforce maximum length constraints on all network-received data structures before processing begins. Utilizing static analysis tools during the software development lifecycle can help identify missing boundary checks in parsing logic. Furthermore, deploying runtime application self-protection solutions or web application firewalls configured to detect anomalous packet sizes can provide an additional layer of defense by dropping malformed traffic before it reaches the vulnerable application code. Regular security audits focusing on memory safety and buffer handling practices are essential to prevent similar vulnerabilities from being introduced into the system architecture.
