CVE-2025-47343 is a vulnerability classified under CWE-822 (Untrusted Pointer Dereference) found in multiple Qualcomm Snapdragon products, including various FastConnect modules, WCD series audio components, and Snapdragon chipsets such as Cologne and SC8380XP. The issue arises during the processing of video sessions when setting video parameters, where improper handling of pointers leads to memory corruption. This corruption can be exploited to execute arbitrary code, escalate privileges, or cause denial of service by crashing the affected component. The vulnerability requires local access with low privileges (PR:L), no user interaction (UI:N), and has low attack complexity (AC:L), making it feasible for attackers who have some foothold on the device. The scope is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), indicating that successful exploitation can fully compromise the device’s security. The affected product list is extensive, covering many Snapdragon platforms widely used in mobile devices, IoT, and embedded systems. Although no exploits are known in the wild yet, the vulnerability’s nature and broad impact necessitate urgent attention. Qualcomm has not yet published patches, so mitigation currently relies on limiting local access and monitoring for suspicious activity.

For European organizations, the impact of CVE-2025-47343 is significant, especially those relying on Snapdragon-based devices for critical communications, mobile computing, or embedded systems. Exploitation could lead to unauthorized access to sensitive data, disruption of services, and potential lateral movement within networks. Telecommunications providers, mobile device manufacturers, and enterprises with Bring Your Own Device (BYOD) policies are particularly at risk. The vulnerability could be leveraged to compromise smartphones, tablets, or IoT devices, undermining data confidentiality and operational integrity. Given the high integration of Qualcomm Snapdragon components in European consumer and industrial devices, the threat could affect sectors such as finance, healthcare, and government services, where data protection and service availability are paramount. The requirement for local access limits remote exploitation but does not eliminate risk, as attackers may use social engineering or malware to gain initial foothold. The absence of known exploits currently provides a window for proactive defense, but the high severity score indicates potential for severe damage if exploited.

1. Monitor Qualcomm’s advisories closely and apply security patches immediately once released to address CVE-2025-47343. 2. Restrict local access to devices containing affected Snapdragon components, enforcing strict physical and logical access controls. 3. Implement endpoint detection and response (EDR) solutions to identify anomalous behavior indicative of exploitation attempts targeting video processing components. 4. Harden device configurations by disabling unnecessary video session features or services that interact with vulnerable modules where feasible. 5. Educate users and administrators about the risks of local privilege escalation vulnerabilities and enforce least privilege principles to minimize attack surface. 6. For organizations deploying IoT or embedded systems with affected chipsets, segment networks to limit lateral movement in case of compromise. 7. Conduct regular security audits and penetration testing focusing on local privilege escalation vectors. 8. Collaborate with device vendors to ensure timely firmware updates and verify patch deployment status across the device fleet.
