CVE-2025-47349 is a vulnerability classified under CWE-823 (Use of Out-of-range Pointer Offset) affecting Qualcomm Snapdragon components, specifically in the processing of escape calls which leads to memory corruption. The affected products include a range of Snapdragon chipsets and modules such as FastConnect 6900 and 7800, QCC2072, SC8380XP, multiple WCD and WSA series chips, and several X-series components. The flaw arises when the software incorrectly calculates or uses pointer offsets beyond the allocated memory bounds, potentially allowing an attacker to corrupt memory. This corruption can result in unauthorized disclosure of sensitive information (confidentiality impact), modification of data or code (integrity impact), and disruption or crash of the affected system (availability impact). The CVSS v3.1 score of 7.8 reflects a high severity, with attack vector local (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). Exploitation requires local access but no user interaction, making it a significant threat in environments where attackers can gain limited system access. No public exploits are known yet, but the vulnerability's characteristics suggest it could be leveraged for privilege escalation or denial of service. Qualcomm has not yet published patches, so affected organizations must monitor for updates and apply them promptly once available.

For European organizations, the impact of CVE-2025-47349 is considerable due to the widespread use of Qualcomm Snapdragon chipsets in mobile devices, IoT equipment, and embedded systems. Confidential data processed or stored on affected devices could be exposed or altered, undermining data privacy and integrity obligations under regulations like GDPR. The availability impact could disrupt critical communications or operational technology relying on these components, affecting sectors such as telecommunications, manufacturing, and public services. The local attack vector means that insider threats or attackers who gain physical or local network access could exploit this vulnerability to escalate privileges or cause system failures. This risk is amplified in environments with Bring Your Own Device (BYOD) policies or where endpoint security is less stringent. The absence of known exploits currently provides a window for proactive defense, but the high severity score necessitates urgent attention to prevent potential exploitation.

Given the lack of available patches, European organizations should implement several targeted mitigations: 1) Enforce strict local access controls to limit who can interact with devices containing affected Snapdragon components, including physical security and network segmentation. 2) Monitor device behavior for signs of memory corruption or abnormal escape call processing, using endpoint detection and response (EDR) tools tailored to embedded systems where possible. 3) Restrict installation and execution of untrusted local applications or code that could trigger the vulnerability. 4) Collaborate closely with device manufacturers and Qualcomm to obtain timely security updates and apply patches immediately upon release. 5) Conduct thorough inventory and asset management to identify all devices with affected chipsets, including IoT and embedded devices often overlooked. 6) Educate IT and security teams about the vulnerability specifics to improve detection and response capabilities. 7) Consider deploying additional runtime protections such as memory protection mechanisms or sandboxing where feasible to mitigate exploitation impact.
