CVE-2025-27068 is a high-severity vulnerability classified as CWE-126 (Buffer Over-read) affecting multiple Qualcomm Snapdragon platforms and related components. The flaw arises from improper handling of an IOCTL (Input/Output Control) command that allows memory corruption by reading beyond the intended buffer boundaries using an arbitrary address. This vulnerability impacts a broad range of Qualcomm products, including FastConnect wireless subsystems (6200, 6900, 7800), Snapdragon compute platforms (7c, 7c Gen 2, 8cx Gen 3), and various audio and wireless components (WCD9380, WCD9385, WSA8830 series). The vulnerability is exploitable with low attack complexity and requires low privileges (PR:L) but no user interaction (UI:N). The CVSS v3.1 base score is 7.8, indicating a high severity level. The vulnerability can lead to significant confidentiality, integrity, and availability impacts, including potential arbitrary code execution or system crashes due to memory corruption. Although no known exploits are currently reported in the wild, the broad product impact and high severity warrant urgent attention. The vulnerability affects the kernel or driver-level code that processes IOCTL commands, which are commonly used for device control and communication between user space and kernel space, making exploitation feasible by local attackers or potentially through compromised applications. The lack of available patches at the time of publication increases the risk window for affected devices.

For European organizations, this vulnerability poses a substantial risk, especially those relying on devices powered by affected Qualcomm Snapdragon platforms. These platforms are widely used in mobile devices, laptops, IoT devices, and embedded systems. Exploitation could allow attackers to escalate privileges, execute arbitrary code, or cause denial of service, potentially leading to data breaches, disruption of critical services, or compromise of sensitive information. Industries such as telecommunications, finance, healthcare, and manufacturing that deploy Snapdragon-based devices for communication or operational technology could face operational disruptions and regulatory compliance challenges under GDPR if personal data confidentiality is compromised. The vulnerability's ability to impact confidentiality, integrity, and availability simultaneously makes it a critical concern for maintaining secure and resilient IT infrastructures across Europe.

1. Immediate inventory and identification of all devices using affected Qualcomm Snapdragon platforms within the organization. 2. Monitor Qualcomm and device vendors for official patches or firmware updates addressing CVE-2025-27068 and apply them promptly. 3. Until patches are available, implement strict access controls to limit local user privileges and restrict access to devices that process IOCTL commands. 4. Employ endpoint detection and response (EDR) solutions to monitor for anomalous behavior indicative of exploitation attempts, such as unusual IOCTL calls or memory access patterns. 5. Harden device configurations by disabling unnecessary services or interfaces that could be leveraged to trigger the vulnerability. 6. For critical environments, consider network segmentation to isolate vulnerable devices and reduce attack surface exposure. 7. Engage with device manufacturers to obtain security advisories and coordinate vulnerability management efforts. 8. Conduct security awareness training for IT staff to recognize and respond to potential exploitation signs related to this vulnerability.
