Technical Analysis

CVE-2025-27054 is an out-of-bounds write vulnerability classified under CWE-787, discovered in Qualcomm Snapdragon products. The vulnerability is triggered during the reboot process when the system processes a malformed license file, leading to memory corruption. This corruption can be exploited to overwrite memory regions beyond their intended bounds, potentially allowing attackers to execute arbitrary code with elevated privileges. The vulnerability affects an extensive list of Snapdragon platforms, including mobile processors (e.g., Snapdragon 8 Gen series, Snapdragon 7 and 6 series), IoT modems, automotive platforms, wearable platforms, and various modem-RF systems. The CVSS v3.1 score is 7.8, indicating high severity, with attack vector Local (L), low attack complexity (L), requiring privileges (PR:L), no user interaction (UI:N), and impacting confidentiality, integrity, and availability at a high level. No public exploits are currently known. The vulnerability's root cause is improper bounds checking when parsing license files during reboot, which can be malformed by an attacker with local access. Successful exploitation could lead to privilege escalation, arbitrary code execution, and full system compromise on affected devices. This poses risks to devices that rely on Snapdragon chips for critical functions, including smartphones, IoT devices, automotive systems, and wearables.

Potential Impact

For European organizations, the impact of CVE-2025-27054 is significant due to the widespread use of Qualcomm Snapdragon chips in consumer and enterprise devices. Mobile devices used by employees could be compromised, leading to data breaches, espionage, or ransomware deployment. IoT and automotive devices using affected Snapdragon platforms may face operational disruptions or safety risks if attackers exploit the vulnerability to gain control. The vulnerability's ability to compromise confidentiality, integrity, and availability simultaneously means sensitive corporate and personal data could be exposed or manipulated. Critical infrastructure relying on Snapdragon-based embedded systems could be targeted, affecting sectors like automotive manufacturing, telecommunications, and smart city deployments. The requirement for local privileges limits remote exploitation but insider threats or malware already on devices could leverage this flaw to escalate privileges and propagate attacks. The lack of known exploits provides a window for proactive mitigation, but the broad product impact demands urgent attention to patch management and device security.

Mitigation Recommendations

1. Monitor Qualcomm and device vendors for official patches addressing CVE-2025-27054 and apply them promptly across all affected devices and platforms. 2. Implement strict controls on access to devices and systems that process license files, limiting local privilege escalation opportunities. 3. Employ runtime protections such as memory corruption mitigations (e.g., DEP, ASLR) on affected devices where possible. 4. Validate and restrict license file formats and sources to prevent injection of malformed files, including integrity checks and cryptographic verification. 5. For enterprise environments, enforce endpoint detection and response (EDR) solutions to detect anomalous reboot or license file processing activities. 6. Conduct security audits on IoT and automotive devices to identify vulnerable Snapdragon platforms and isolate or upgrade them. 7. Educate users and administrators about the risks of local privilege escalation vulnerabilities and the importance of device hygiene. 8. Where feasible, implement network segmentation to limit lateral movement from compromised devices. 9. Maintain an inventory of all Snapdragon-based devices in use to prioritize patching and risk assessment. 10. Collaborate with suppliers and service providers to ensure timely vulnerability disclosure and remediation.
