Attack Chain

1. A malicious application is installed on the target device, leveraging existing permissions or exploiting other vulnerabilities for installation.
2. The malicious application gains low-level privileges, potentially through privilege escalation techniques, if necessary.
3. The application interacts with the camera sensor through input/output control codes (IOCTLs).
4. The application crafts a specific IOCTL request with an invalid output buffer size or memory address.
5. The camera sensor processing component attempts to write data to the invalid output buffer.
6. This write operation triggers a memory corruption condition due to the out-of-bounds access.
7. The memory corruption can lead to a denial of service, causing the device to crash or become unresponsive.
8. In more severe scenarios, the memory corruption could be leveraged to achieve arbitrary code execution, allowing the attacker to gain full control of the device.

Impact

Successful exploitation of CVE-2025-47405 can lead to a range of negative consequences, from denial of service to arbitrary code execution. If an attacker gains code execution, they could potentially steal sensitive data, install malware, or use the device as part of a botnet. The exact number of affected devices is unknown, but given Qualcomm’s widespread presence in mobile devices and other embedded systems, the potential impact is significant. Sectors affected would primarily be consumer electronics and potentially industrial control systems using affected Qualcomm components.

Recommendation

• Monitor for unexpected or malicious applications interacting with camera sensor devices, using process creation logs (logsource: process_creation, product: android).
• Implement endpoint detection rules to detect suspicious process memory access patterns potentially related to memory corruption attempts (logsource: process_creation, product: android).
• Refer to Qualcomm’s security bulletin for affected devices and patch information (references: https://docs.qualcomm.com/product/publicresources/securitybulletin/may-2026-bulletin.html).
