Overview
The CVE-2025-26440 vulnerability is a newly identified security flaw found in multiple functions of CameraService.cpp. This vulnerability could lead to unauthorized camera access from the background, possibly resulting in local privilege escalation. It is critical as it allows data leakage or system compromise without any user interaction, thus affecting the confidentiality, integrity, and availability of the system.

How the Exploit Works
The vulnerability exists due to a permissions bypass in multiple functions of CameraService.cpp. This design flaw enables an attacker to invoke the camera service from the background without requiring any permissions. As a result, an attacker could potentially escalate privileges locally and execute unwanted actions without user knowledge.
Conceptual Example Code
While no specific exploit code exists for this vulnerability, a potential exploitation scenario might involve an attacker running a malicious application on the device. In pseudocode, this could look like the following:
app_process = system.getProcess("CameraService.cpp")
if app_process.hasPermission("CAMERA"):
app_process.startCamera()
else:
print("Cannot start camera")In the above scenario, the attacker’s application would not need the `CAMERA` permission, as the vulnerability bypasses this check.
Mitigation Guidance
To mitigate the CVE-2025-26440 vulnerability, it is recommended to apply the vendor patch once available. In the interim, the usage of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. Regularly updating and patching software can also help to reduce the risk of exploitation.
