CVE-2025-47325 is a vulnerability classified under CWE-822 (Untrusted Pointer Dereference) found in multiple Qualcomm Snapdragon chipsets, including a broad range of IPQ, QCA, QCN, and SDX series processors. The flaw arises during the processing of system calls when invalid parameters are passed, leading to the dereferencing of untrusted pointers. This results in an information disclosure vulnerability, allowing an attacker with local privileges to potentially read sensitive memory contents that should be protected. The vulnerability does not affect system integrity or availability, nor does it require user interaction, but it does require the attacker to have some level of local access (low privileges). The CVSS v3.1 score is 6.5 (medium severity), with a vector indicating local attack vector, low attack complexity, low privileges required, no user interaction, and a scope change due to confidentiality impact. The affected Snapdragon versions span many embedded and IoT-focused chipsets commonly deployed in networking equipment, mobile devices, and industrial applications. No public exploits are known at this time, and Qualcomm has not yet released patches, though the vulnerability is publicly disclosed as of December 2025. The flaw could be exploited by malicious insiders or attackers who gain local access to devices to extract sensitive information from memory, potentially leaking cryptographic keys, credentials, or other confidential data.

For European organizations, the primary impact of CVE-2025-47325 is the potential leakage of sensitive information from devices running affected Qualcomm Snapdragon chipsets. This is particularly concerning for sectors relying heavily on embedded systems and IoT devices, such as telecommunications, critical infrastructure, manufacturing, and smart city deployments. Confidentiality breaches could expose cryptographic keys, user credentials, or proprietary data, leading to further compromise or espionage. Since the vulnerability requires local access, the risk is higher in environments where physical or network access to devices is less controlled. The lack of impact on integrity and availability limits the threat to data exposure rather than service disruption. However, the scope change in CVSS indicates that the vulnerability could affect components beyond the immediate system call context, potentially broadening the attack surface. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits post-disclosure. European organizations with extensive use of Qualcomm Snapdragon-based networking equipment or IoT devices should consider this vulnerability a significant confidentiality risk.

1. Monitor Qualcomm’s advisories closely and apply security patches promptly once they become available for affected Snapdragon chipsets. 2. Restrict local access to devices running vulnerable chipsets by enforcing strict physical security and network segmentation to limit potential attackers’ ability to execute system calls with crafted parameters. 3. Implement robust access controls and privilege management to minimize the number of users or processes with local privileges capable of exploiting the vulnerability. 4. Employ runtime monitoring and anomaly detection tools to identify unusual system call behavior or memory access patterns indicative of exploitation attempts. 5. For embedded and IoT devices, consider firmware integrity verification and secure boot mechanisms to prevent unauthorized code execution that could leverage this vulnerability. 6. Conduct regular security audits of devices using affected Snapdragon variants to identify and remediate potential attack vectors. 7. Collaborate with vendors and suppliers to ensure timely updates and security support for affected hardware components.
