CVE-2025-43993 is a high-severity vulnerability classified under CWE-428, which pertains to Unquoted Search Path or Element issues. This vulnerability affects the Dell Wireless 5932e adapter and Qualcomm Snapdragon X62 Firmware and GNSS/GPS Driver versions prior to 3.2.0.22. The core issue arises from the way the affected software handles file paths that are not enclosed in quotes. When a path contains spaces and is unquoted, the operating system may incorrectly interpret the path, potentially allowing an attacker to execute malicious code by placing a crafted executable in a location that is searched prior to the legitimate executable. This vulnerability requires the attacker to have local access with low privileges, meaning they must already have some level of access to the system but do not need administrative rights. Exploitation does not require user interaction, and the vulnerability can lead to full compromise of confidentiality, integrity, and availability of the affected system. The CVSS v3.1 score of 7.8 reflects the high impact and relatively low complexity of exploitation, with no user interaction required. Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to the potential for privilege escalation and arbitrary code execution. The lack of available patches at the time of this report increases the urgency for mitigation and monitoring. The vulnerability affects firmware and drivers that are integral to wireless communication and GPS functionality, which are critical components in many enterprise and consumer devices, making this a notable security concern.

For European organizations, this vulnerability could have serious implications, especially for those relying on Dell Wireless 5932e adapters and Qualcomm Snapdragon X62 components in their infrastructure. The ability for a low-privileged local attacker to execute arbitrary code could lead to unauthorized access to sensitive data, disruption of wireless communications, and potential manipulation of GPS data, which could affect location-based services and operational integrity. Industries such as telecommunications, transportation, logistics, and critical infrastructure that depend on accurate GPS and reliable wireless connectivity are particularly at risk. Additionally, organizations with bring-your-own-device (BYOD) policies or shared workstations may face increased exposure due to the local access requirement. The compromise of wireless drivers and firmware could also facilitate lateral movement within networks, enabling attackers to escalate privileges and access broader network resources. Given the high confidentiality, integrity, and availability impact, exploitation could result in data breaches, operational downtime, and reputational damage for affected European entities.

Immediate mitigation should focus on minimizing local access to systems with affected hardware and software. Organizations should enforce strict access controls and monitor for unusual local activity. Since no patches are currently available, it is critical to implement application whitelisting to prevent unauthorized executables from running in directories that are part of the system's search path. Administrators should audit and correct unquoted paths in the system environment variables and startup scripts to ensure all paths containing spaces are properly quoted. Endpoint detection and response (EDR) solutions should be tuned to detect suspicious process creation events related to wireless driver components. Network segmentation can limit the potential for lateral movement if exploitation occurs. Users should be educated about the risks of local access and encouraged to report any suspicious behavior. Once Dell releases a patch or firmware update, organizations must prioritize timely deployment. Additionally, maintaining up-to-date inventories of affected devices will aid in targeted remediation efforts.
