CVE-2025-27054 is an out-of-bounds write vulnerability classified under CWE-787 that affects a vast array of Qualcomm Snapdragon chipsets and platforms. The vulnerability arises from improper handling of malformed license files during the reboot process, leading to memory corruption. This memory corruption can be exploited to overwrite critical memory regions, potentially allowing an attacker with limited privileges to escalate their access, execute arbitrary code, or cause system instability or denial of service. The vulnerability affects a broad spectrum of Qualcomm products, including mobile platforms (e.g., Snapdragon 8 Gen series, Snapdragon 7 and 6 series), IoT modems, automotive platforms, wearable platforms, and compute platforms. The CVSS v3.1 score of 7.8 reflects a high severity, with attack vector local (AV:L), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), and impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). The flaw is triggered during device reboot when processing license files, indicating that exploitation requires local access and the ability to provide or manipulate license files. No public exploits are known at this time, but the extensive affected product list and critical impact warrant urgent mitigation. The vulnerability could be leveraged to compromise device security, extract sensitive data, or disrupt device functionality. Qualcomm has published the vulnerability but has not yet released patches, emphasizing the need for vigilance and proactive defense.

For European organizations, the impact of CVE-2025-27054 is substantial due to the widespread use of Qualcomm Snapdragon chipsets in smartphones, IoT devices, automotive systems, and industrial equipment. Confidentiality breaches could expose sensitive corporate or personal data, while integrity compromises could allow attackers to alter device behavior or firmware. Availability impacts could disrupt critical services, especially in sectors relying on IoT and automotive platforms, such as manufacturing, transportation, and smart city infrastructure. The vulnerability's requirement for local privileges means insider threats or compromised devices could be leveraged to escalate attacks. The broad product range affected increases the attack surface, complicating risk management. European enterprises with large mobile workforces, connected vehicle fleets, or industrial IoT deployments face elevated risks. Additionally, the lack of current patches means organizations must rely on compensating controls to mitigate exposure. The potential for supply chain attacks exploiting this vulnerability also poses a strategic risk to European technology ecosystems.

1. Monitor Qualcomm and device vendors for official patches and apply them promptly across all affected devices. 2. Implement strict validation and integrity checks for license files to prevent malformed or malicious files from being processed during reboot. 3. Restrict local access to devices, enforcing strong authentication and limiting privilege escalation opportunities. 4. Employ endpoint detection and response (EDR) solutions to monitor for abnormal reboot behaviors or memory corruption indicators. 5. Harden device reboot processes by isolating license file processing in secure execution environments or sandboxes. 6. Conduct thorough inventory and asset management to identify all devices using affected Qualcomm platforms within the organization. 7. Collaborate with supply chain partners to ensure devices are updated and secure before deployment. 8. Educate internal teams on the risks of local privilege misuse and enforce strict access controls. 9. Consider network segmentation to isolate critical IoT and automotive systems from general enterprise networks. 10. Prepare incident response plans specific to exploitation scenarios involving device firmware or reboot vulnerabilities.
