CVE-2025-47326 is a high-severity vulnerability identified in multiple Qualcomm Snapdragon platforms and related wireless connectivity chipsets. The vulnerability is classified as CWE-126, which corresponds to a buffer over-read condition. Specifically, this flaw occurs during the handling of command data in power control processing routines. A buffer over-read happens when a program reads data beyond the boundaries of a buffer, potentially leading to unexpected behavior or system instability. In this case, the vulnerability results in a transient denial-of-service (DoS) condition, meaning the affected device or component may temporarily become unresponsive or crash when processing certain crafted command data. The vulnerability affects a wide range of Qualcomm products, including various Snapdragon modem-RF systems (e.g., X65, X72, X75), FastConnect wireless subsystems, Immersive Home platforms, and numerous IPQ and QCA series chipsets commonly used in networking equipment, mobile devices, and IoT hardware. The CVSS v3.1 score is 7.5 (high), reflecting that the attack vector is network-based (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and impacts availability (A:H) without affecting confidentiality or integrity. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability’s root cause is a failure to properly validate or limit the size of input command data during power control operations, leading to out-of-bounds memory reads. This can cause system crashes or reboots, disrupting normal device operation. Given the broad product impact, this vulnerability could affect a wide array of devices that rely on Qualcomm Snapdragon chipsets for wireless communication and processing, including smartphones, routers, gateways, and embedded systems.

For European organizations, the impact of CVE-2025-47326 can be significant, particularly for those relying on networking infrastructure, mobile communications, and IoT devices powered by Qualcomm Snapdragon chipsets. The transient DoS condition could disrupt critical communications, degrade network availability, and cause service interruptions. Telecommunications providers, enterprises with large mobile device fleets, and industries deploying IoT solutions (e.g., smart buildings, manufacturing, healthcare) may experience operational disruptions. The vulnerability’s network-based attack vector means that attackers can potentially exploit it remotely without authentication or user interaction, increasing the risk of widespread impact. Although the vulnerability does not compromise data confidentiality or integrity, the availability impact alone can lead to downtime, loss of productivity, and potential cascading failures in dependent systems. In sectors such as finance, healthcare, and critical infrastructure, even transient outages can have severe consequences. Additionally, the broad range of affected Qualcomm products means that patching and mitigation efforts may be complex and require coordination with multiple vendors and device manufacturers. The absence of known exploits in the wild currently reduces immediate risk but does not preclude future exploitation attempts, especially as threat actors analyze the vulnerability details post-disclosure.

To mitigate the risk posed by CVE-2025-47326, European organizations should take a multi-layered approach: 1) Inventory and identify all devices and infrastructure components using affected Qualcomm Snapdragon chipsets, including mobile devices, routers, gateways, and embedded systems. 2) Engage with device manufacturers and vendors to obtain firmware or software updates addressing this vulnerability as soon as patches become available. Given the lack of patch links currently, maintain close monitoring of vendor advisories and Qualcomm security bulletins. 3) Implement network segmentation and access controls to limit exposure of vulnerable devices to untrusted networks, reducing the attack surface. 4) Employ intrusion detection and prevention systems (IDS/IPS) with updated signatures to detect anomalous traffic patterns that may exploit this vulnerability. 5) For critical systems, consider temporary workarounds such as disabling non-essential wireless interfaces or power control features if feasible and supported by vendors. 6) Maintain robust incident response plans to quickly identify and remediate any service disruptions potentially caused by exploitation attempts. 7) Educate IT and security teams about the vulnerability’s nature and signs of exploitation to enhance detection capabilities. 8) Monitor threat intelligence feeds for any emerging exploit code or attack campaigns targeting this vulnerability to adjust defenses promptly.
