CVE-2025-47368: CWE-126 Buffer Over-read in Qualcomm, Inc. Snapdragon
Memory corruption when dereferencing an invalid userspace address in a user buffer during MCDM IOCTL processing.
AI Analysis
Technical Summary
CVE-2025-47368 is a buffer over-read vulnerability classified under CWE-126, discovered in Qualcomm Snapdragon components including FastConnect 6900, 7800, SC8380XP, WCD9380, WCD9385, WSA8840, WSA8845, and WSA8845H. The vulnerability occurs during the processing of MCDM IOCTL calls, where the kernel dereferences an invalid userspace address in a user buffer, leading to memory corruption. This flaw can be exploited by a low-privileged attacker (PR:L) without requiring user interaction (UI:N), making it relatively accessible in scenarios where local access is possible. The CVSS 3.1 score of 7.8 reflects high severity, with impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). Exploitation could allow attackers to read sensitive memory contents, corrupt kernel memory, or cause system crashes, potentially leading to privilege escalation or denial of service. The affected components are integral to wireless connectivity in many mobile and IoT devices, making this vulnerability critical in environments relying on Qualcomm Snapdragon chipsets. No public exploits are known yet, but the vulnerability's nature suggests that weaponization is feasible. The lack of available patches at the time of publication increases the urgency for mitigation strategies.
Potential Impact
For European organizations, the impact of CVE-2025-47368 is significant due to the widespread use of Qualcomm Snapdragon chipsets in smartphones, tablets, and IoT devices. Confidentiality breaches could expose sensitive corporate or personal data, while integrity compromises might allow attackers to manipulate device behavior or firmware. Availability impacts could disrupt wireless communications, leading to denial of service in critical business operations or consumer services. Industries such as telecommunications, finance, healthcare, and manufacturing, which rely heavily on mobile and IoT connectivity, are particularly vulnerable. Additionally, the vulnerability could be leveraged in targeted attacks against high-value individuals or infrastructure, especially where local access to devices is possible. The absence of known exploits currently provides a window for proactive defense, but the potential for rapid exploitation once weaponized necessitates immediate attention.
Mitigation Recommendations
1. Monitor Qualcomm and device manufacturers for official patches and apply them promptly once released. 2. Restrict access to MCDM IOCTL interfaces by enforcing strict access controls and limiting permissions to trusted processes only. 3. Implement device-level security policies that prevent untrusted applications from invoking vulnerable IOCTL calls. 4. Employ runtime protection mechanisms such as kernel memory protection and address space layout randomization (ASLR) to reduce exploitation success. 5. Conduct regular security audits and vulnerability scans on devices using affected Snapdragon components. 6. Educate users and administrators about the risks of local privilege escalation and the importance of device hygiene. 7. Deploy endpoint detection and response (EDR) solutions capable of detecting anomalous IOCTL usage or memory corruption indicators. 8. For enterprise environments, consider network segmentation to isolate vulnerable devices and limit lateral movement in case of compromise.
