This vulnerability is a multi-threaded race condition within the camera framework module of Huawei devices. A race condition occurs when the execution order of concurrent threads accessing shared resources (like camera buffers or state variables) is not properly synchronized. If an attacker with high local privileges can manipulate timing, they could cause one thread to read or write to a resource (e.g., a camera state flag or an image buffer pointer) while another thread is performing a conflicting operation on it. This desynchronization can lead to an invalid state, such as accessing freed memory (use-after-free) or corrupting critical data structures. The outcome is typically an application or kernel crash in the camera service, disrupting the device’s availability by disabling the camera or causing a system reboot. The attack requires local access and high privileges (PR:H), making it a local integrity and availability issue.
Platform: Huawei devices
Version: Affected EMUI/HarmonyOS
Vulnerability: Race Condition
Severity: Medium
date: 12/08/2025
Prediction: 2025-12-22
What Undercode Say:
`ps -A | grep camera`
`logcat | grep -i “camera.error\|race”`
`find /vendor/lib -name “camera.so”`
How Exploit:
A malicious high-privilege app triggers rapid, concurrent camera API calls (open/close/configure) to create timing windows where framework threads conflict on shared state, leading to a crash of the camera hal or provider service, denying camera functionality.
Protection from this CVE
Apply vendor security update. Minimize local privileged accounts. Use kernel hardening (e.g., SELinux). Code review for thread synchronization in camera HAL.
Impact:
Local Denial-of-Service (camera unavailable), potential system instability, requires high local privileges.
