CVE-2025-47382 is a vulnerability classified under CWE-863 (Incorrect Authorization) affecting Qualcomm Snapdragon chipsets and associated platforms. The flaw arises from improper authorization checks in the boot loader during the loading of firmware, specifically when invalid firmware is processed. This leads to memory corruption, which can be exploited by a local attacker with limited privileges (PR:L) to execute arbitrary code or cause denial of service. The vulnerability impacts a broad spectrum of Qualcomm products, including FastConnect modules, various QCA and QCM chipsets, Snapdragon mobile platforms (from Snapdragon 4 Gen 1 to Snapdragon 8 Gen 3), wearable platforms, and video collaboration platforms. The CVSS v3.1 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), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). The vulnerability could allow attackers to load malicious firmware or manipulate the boot process, potentially gaining persistent control over the device at a low privilege level. No patches are currently linked, and no known exploits are reported in the wild, but the risk remains significant due to the critical nature of the boot loader in device security. The vulnerability's exploitation could lead to severe consequences including data theft, device bricking, or persistent malware implantation.

For European organizations, the impact of CVE-2025-47382 is substantial due to the widespread use of Qualcomm Snapdragon chipsets in smartphones, IoT devices, and embedded systems critical to business operations and communications. Confidentiality is at risk as attackers could gain unauthorized access to sensitive data stored or processed on affected devices. Integrity could be compromised by malicious firmware modifications, leading to undetected manipulation of device functions or data. Availability may be disrupted through denial-of-service conditions caused by memory corruption. The local attack vector means that attackers need some form of physical or local access, which could be facilitated in corporate environments through insider threats or compromised devices. The lack of user interaction requirement increases the risk of automated or stealthy attacks. This vulnerability could also affect supply chains relying on Snapdragon-based hardware, impacting sectors such as telecommunications, manufacturing, and critical infrastructure. The absence of known exploits provides a window for proactive mitigation, but the high severity score demands urgent attention to prevent potential exploitation.

1. Monitor Qualcomm and device manufacturers for official patches and firmware updates addressing CVE-2025-47382 and apply them promptly once available. 2. Implement strict access controls to limit local access to devices with affected Snapdragon chipsets, including physical security measures and endpoint protection. 3. Employ device attestation and secure boot mechanisms to detect and prevent unauthorized or invalid firmware loading. 4. Use mobile device management (MDM) solutions to enforce security policies and monitor device integrity in enterprise environments. 5. Conduct regular security audits and firmware integrity checks on critical devices to identify anomalies indicative of exploitation attempts. 6. Educate staff about the risks of local device tampering and enforce policies to minimize insider threats. 7. For IoT deployments, segment networks to isolate vulnerable devices and reduce attack surface exposure. 8. Collaborate with vendors to obtain timely vulnerability disclosures and mitigation guidance. 9. Prepare incident response plans that include scenarios involving firmware-level compromises to enable rapid containment and recovery.
