CVE-2024-53013 is a medium-severity buffer overflow vulnerability (CWE-120) affecting a wide range of Qualcomm Snapdragon platforms and related chipsets. The vulnerability arises from improper handling of input size during the processing of voice call registration, leading to a classic buffer overflow condition. Specifically, the flaw occurs when the system copies data into a buffer without verifying that the input size fits within the allocated buffer boundaries. This can cause memory corruption, which may be exploited to alter program control flow or corrupt data structures. The affected products include numerous Snapdragon mobile platforms (e.g., SD865 5G, Snapdragon 820 Automotive Platform), FastConnect wireless subsystems, Qualcomm Video Collaboration platforms, and various modem and wireless connectivity chipsets. The CVSS v3.1 base score is 6.6, indicating a medium severity with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L. This means the attack requires local access with low privileges, no user interaction, and can lead to low confidentiality impact but high integrity impact and low availability impact. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability's root cause is a classic buffer overflow, which remains a critical class of memory corruption bugs that can be leveraged for privilege escalation or code execution if combined with other vulnerabilities or conditions. Given the broad range of affected hardware, this vulnerability has significant implications for devices relying on Qualcomm Snapdragon chipsets, especially those handling voice call registration processes.

For European organizations, the impact of CVE-2024-53013 can be substantial, particularly for enterprises and service providers relying on devices powered by affected Qualcomm Snapdragon chipsets. These include smartphones, automotive telematics units, IoT devices, and wireless communication modules. The vulnerability could allow attackers with local access—such as malicious apps or compromised internal users—to corrupt memory during voice call registration, potentially leading to privilege escalation or unauthorized code execution. This could compromise device integrity, enabling attackers to intercept or manipulate voice communications, disrupt service, or pivot to other internal systems. In critical sectors such as telecommunications, automotive, healthcare, and industrial control systems, exploitation could undermine operational reliability and data integrity. Furthermore, since many European organizations use mobile devices and embedded systems with these chipsets, the risk extends to mobile workforce security and connected infrastructure. Although exploitation requires local access and low privileges, the widespread deployment of vulnerable devices increases the attack surface. The absence of known exploits currently reduces immediate risk but does not eliminate the potential for future targeted attacks, especially as threat actors develop exploit techniques for buffer overflow conditions in embedded platforms.

To mitigate CVE-2024-53013, European organizations should: 1) Monitor Qualcomm and device vendors for official patches or firmware updates addressing this vulnerability and prioritize timely deployment across all affected devices. 2) Implement strict application whitelisting and privilege management on devices to limit the ability of untrusted or low-privilege applications to interact with voice call registration components. 3) Employ endpoint detection and response (EDR) solutions capable of detecting anomalous behavior indicative of memory corruption or privilege escalation attempts on mobile and embedded devices. 4) Restrict local access to devices, enforcing strong physical security and user authentication to reduce the risk of local exploitation. 5) For organizations deploying IoT or automotive systems with affected chipsets, conduct thorough security assessments and consider network segmentation to isolate vulnerable devices from critical infrastructure. 6) Educate users and administrators about the risks of installing untrusted applications and the importance of applying security updates promptly. 7) Collaborate with device manufacturers and suppliers to verify the vulnerability status of deployed hardware and request security advisories or mitigations specific to their device models. These measures go beyond generic patching by emphasizing access control, monitoring, and supply chain engagement to reduce exploitation likelihood.
