CVE-2025-47387 is a memory corruption vulnerability classified under CWE-822 (Untrusted Pointer Dereference) found in Qualcomm Snapdragon platforms. The flaw arises from improper verification of pointers when processing IOCTL commands related to JPEG data, leading to potential untrusted pointer dereference. This can cause memory corruption, which attackers can exploit to achieve arbitrary code execution, privilege escalation, or denial of service. The vulnerability affects a broad range of Qualcomm products including multiple Snapdragon compute platforms (e.g., 7c, 8c, 8cx series), FastConnect wireless modules, and various WCD and WSA audio components. The CVSS v3.1 base score is 7.8, indicating high severity, with attack vector local (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), and impacting confidentiality, integrity, and availability (C:H/I:H/A:H). Exploitation requires local access but no user interaction, making it a significant risk in environments where attackers can gain limited access. No public exploits are known yet, but the wide range of affected devices and critical nature of the flaw necessitate urgent attention. Qualcomm has not yet published patches, so mitigation currently relies on access controls and monitoring.

The vulnerability poses a critical risk to European organizations using devices with affected Qualcomm Snapdragon platforms, including smartphones, tablets, IoT devices, and compute modules. Successful exploitation can lead to full compromise of the device, allowing attackers to access sensitive data, disrupt services, or pivot within networks. This is particularly concerning for sectors relying on mobile computing and embedded systems, such as telecommunications, manufacturing, healthcare, and critical infrastructure. The confidentiality, integrity, and availability of data and services can be severely impacted. Given the prevalence of Snapdragon chips in consumer and enterprise devices, the attack surface is extensive. The local attack vector means insider threats or malware with limited privileges could exploit this flaw. The lack of user interaction requirement increases the risk of automated or stealthy exploitation once local access is obtained.

1. Immediately restrict access to IOCTL interfaces handling JPEG data to trusted processes and users only, using OS-level access controls or SELinux/AppArmor policies. 2. Monitor system logs and behavior for unusual activity related to JPEG processing or unexpected memory faults. 3. Deploy endpoint detection and response (EDR) solutions capable of detecting memory corruption or privilege escalation attempts. 4. Coordinate with device and platform vendors to obtain and apply security patches as soon as they become available. 5. For managed devices, enforce strict application whitelisting and privilege restrictions to minimize the risk of local exploitation. 6. In environments where patching is delayed, consider network segmentation and limiting physical or remote local access to vulnerable devices. 7. Educate users and administrators about the risk of local exploits and the importance of device hygiene to prevent unauthorized local access.
