CVE-2025-47342 is a use-after-free vulnerability (CWE-416) identified in Qualcomm Snapdragon audio platforms, including QCC5161, QCC7225, QCC7226, QCC7228, and various S3 and S5 Sound Platforms. The vulnerability occurs when multi-profile concurrency is enabled alongside Qualcomm High-Speed (QHS) mode, leading to improper memory management. Specifically, a use-after-free condition arises when the system attempts to access memory that has already been freed, causing transient denial of service (DoS) conditions. This can disrupt audio processing or communication functions dependent on these platforms. The CVSS v3.1 score is 7.1, reflecting high severity due to the network attack vector (AV:N), low attack complexity (AC:L), requirement for privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), no confidentiality impact (C:N), limited integrity impact (I:L), and high availability impact (A:H). Exploitation requires low-level privileges but no user interaction, making it feasible in environments where an attacker has some access. No public exploits have been reported yet, but the vulnerability is significant due to the widespread use of Qualcomm Snapdragon chipsets in consumer and industrial devices. The lack of available patches at the time of publication necessitates interim mitigations. The vulnerability primarily affects audio subsystems, which are critical for communication devices, IoT endpoints, and embedded systems relying on these chipsets.

For European organizations, the primary impact of CVE-2025-47342 is transient denial of service affecting devices using the vulnerable Qualcomm Snapdragon audio platforms. This can disrupt voice communication, audio streaming, and IoT device functionality, potentially impacting business operations reliant on these technologies. Critical sectors such as telecommunications, manufacturing with IoT integration, automotive (infotainment and communication systems), and public safety communications could experience service interruptions. While confidentiality is not directly affected, the integrity of audio processing is partially impacted, and availability is significantly degraded. The requirement for low privileges to exploit means internal threat actors or compromised devices could trigger the vulnerability. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as patches are not yet available. Organizations using affected hardware in Europe must consider the operational risks of audio subsystem failures and potential cascading effects on dependent services.

Organizations should monitor Qualcomm and device vendors for official patches addressing CVE-2025-47342 and apply them promptly once released. Until patches are available, disabling multi-profile concurrency or Qualcomm High-Speed (QHS) mode in device configurations can mitigate the risk by preventing the conditions that trigger the use-after-free. Network segmentation and strict access controls should be enforced to limit exposure of vulnerable devices to untrusted networks and reduce the risk of exploitation by low-privilege attackers. Regular firmware and software updates for devices incorporating affected Snapdragon platforms are essential. Additionally, organizations should implement monitoring for unusual audio subsystem failures or service disruptions that could indicate exploitation attempts. For critical infrastructure, consider fallback communication methods to maintain availability during potential transient DoS events. Collaboration with device manufacturers for timely vulnerability management and incident response planning is recommended.
