CVE-2025-27076 is a high-severity vulnerability classified under CWE-367, indicating a Time-of-check Time-of-use (TOCTOU) race condition in various Qualcomm Snapdragon platforms and related components. This vulnerability arises due to improper handling of simultaneous requests via an escape path, leading to memory corruption. The affected products include a broad range of Qualcomm Snapdragon SoCs and connectivity modules such as FastConnect series (6200 through 7800), multiple QCA and QCM chipsets, Snapdragon 7c, 8c, and 8cx compute platforms, as well as audio and wireless subsystem components (WCD and WSA series). The vulnerability is exploitable locally (AV:L), requires low attack complexity (AC:L), and low privileges (PR:L), but no user interaction (UI:N) is needed. The impact scope is unchanged (S:U), but the confidentiality, integrity, and availability impacts are all high (C:H/I:H/A:H), indicating that exploitation could lead to full compromise of affected devices. The root cause is a race condition where the system checks a resource state and uses it without proper synchronization, allowing an attacker to manipulate the timing of operations to cause memory corruption. This can result in arbitrary code execution, privilege escalation, or denial of service on affected Snapdragon-based devices. No known exploits are currently reported in the wild, and no patches have been linked yet, highlighting the importance of proactive mitigation and monitoring. Given the widespread use of Qualcomm Snapdragon platforms in mobile devices, laptops, and IoT devices, this vulnerability poses a significant risk to device security and user data integrity.

For European organizations, this vulnerability presents a substantial risk due to the extensive deployment of Qualcomm Snapdragon-based devices across consumer electronics, enterprise laptops, and IoT infrastructure. Exploitation could lead to unauthorized access, data breaches, and disruption of critical services, especially in sectors relying on mobile computing and edge devices such as telecommunications, finance, healthcare, and manufacturing. The high impact on confidentiality, integrity, and availability means sensitive corporate and personal data could be exposed or manipulated. Additionally, the local attack vector with low complexity and privilege requirements increases the likelihood of exploitation by insiders or malware that gains limited access. The lack of user interaction needed further lowers the barrier for automated or stealthy attacks. European organizations with Bring Your Own Device (BYOD) policies or those deploying Snapdragon-powered edge devices should be particularly vigilant. The vulnerability could also affect embedded systems in critical infrastructure, potentially impacting operational technology environments. The absence of known exploits currently provides a window for mitigation, but the broad affected product range and lack of patches necessitate immediate risk assessment and remediation planning.

1. Monitor Qualcomm and device vendor advisories closely for official patches or firmware updates addressing CVE-2025-27076 and apply them promptly. 2. Implement strict access controls and endpoint protection to limit local privilege escalation opportunities, including restricting untrusted applications and enforcing least privilege principles. 3. Employ runtime application self-protection (RASP) and behavior-based anomaly detection on devices to identify suspicious memory corruption or race condition exploitation attempts. 4. For enterprise environments, enforce device compliance policies that restrict use of vulnerable Snapdragon-based devices until patched. 5. Use virtualization or containerization where possible to isolate critical applications from potentially compromised hardware components. 6. Conduct thorough security audits and penetration testing focusing on race condition vulnerabilities in device firmware and drivers. 7. Educate users and administrators about the risks of local exploitation and encourage reporting of unusual device behavior. 8. For IoT deployments, segment networks to limit lateral movement if a device is compromised. 9. Collaborate with device manufacturers to prioritize vulnerability remediation and request transparency on patch timelines. 10. Maintain up-to-date backups and incident response plans to mitigate potential damage from exploitation.
