CVE-2025-47332 is a Time-of-check to Time-of-use (TOCTOU) race condition vulnerability classified under CWE-367, affecting numerous Qualcomm Snapdragon chipsets and FastConnect wireless connectivity modules. The vulnerability arises from improper handling of configuration calls originating from userspace, leading to memory corruption. This race condition occurs when the system checks a condition and then uses the resource based on that check, but the state changes between these two operations, allowing an attacker to exploit the timing window. The affected products include a broad range of Snapdragon mobile platforms (from Snapdragon 4 Gen 2 to Snapdragon 8+ Gen 2), FastConnect wireless subsystems (6200 through 7800 series), and various Qualcomm wireless connectivity chips (QCA, QCM, QCS, WCD, WCN, WSA series). The CVSS 3.1 base score is 6.7, indicating medium severity, with an attack vector of local (AV:L), low attack complexity (AC:L), requiring high privileges (PR:H), 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 allows an attacker with elevated privileges on the device to trigger memory corruption, potentially leading to privilege escalation, arbitrary code execution, or denial of service. No public exploits are known at this time, and no patches have been linked yet, indicating the need for vigilance and prompt patching once available. The flaw is particularly critical in environments where Snapdragon chipsets are embedded in critical communication infrastructure or widely deployed mobile devices.

For European organizations, the impact of CVE-2025-47332 can be significant due to the widespread use of Qualcomm Snapdragon chipsets in smartphones, IoT devices, and embedded systems. Exploitation could lead to unauthorized access to sensitive data, disruption of device functionality, or complete device compromise. Telecommunications providers, enterprises relying on mobile workforce devices, and critical infrastructure sectors using Snapdragon-powered equipment could face operational disruptions and data breaches. The requirement for high privileges limits remote exploitation but insider threats or malware with elevated rights could leverage this vulnerability. The memory corruption could also be chained with other vulnerabilities to escalate attacks. Given the prevalence of affected devices in Europe, the vulnerability poses a risk to confidentiality, integrity, and availability of communications and data processing, potentially impacting privacy compliance and operational continuity.

Organizations should monitor Qualcomm’s security advisories closely and apply patches promptly once released. Until patches are available, restrict access to privileged accounts and enforce strict access controls on devices using affected Snapdragon platforms. Employ runtime protection mechanisms such as memory protection and anomaly detection to identify suspicious configuration calls. Conduct regular audits of device firmware and software to detect unauthorized modifications. For enterprise mobile devices, enforce mobile device management (MDM) policies that limit installation of untrusted applications and privilege escalation. Network segmentation can reduce the risk of lateral movement if a device is compromised. Collaborate with device vendors and service providers to ensure timely updates and incident response readiness. Additionally, educate users and administrators about the risks of privilege escalation vulnerabilities and the importance of applying security updates.
