The CVE-2025-66322 is a multi-thread race condition vulnerability in Huawei’s camera framework module. Race conditions occur when multiple threads access shared resources concurrently without proper synchronization, leading to unpredictable behavior. In this case, the vulnerability stems from improper locking or timing windows in the camera framework’s code. When exploited, it can cause threads to interfere with each other, potentially corrupting data or crashing the module. This affects the availability of the camera services. The attack requires local access (AV:L) and low attack complexity (AC:L), but high privileges (PR:H). No user interaction is needed (UI:N). The scope is unchanged (S:U), with no confidentiality impact (C:N), low integrity impact (I:L), and high availability impact (A:H). Essentially, an attacker with local high privileges could trigger the race condition to disrupt camera functionality or alter data, leading to denial of service or minor integrity issues. The vulnerability is rated medium due to the high privilege requirement and local access vector.
Platform: Huawei Technologies

Vulnerability: Multi-thread race condition
Severity: Medium
date: 2025-12-08
Prediction: Patch expected TBA
What Undercode Say:
Analytics
– `ps aux | grep camera`
– `cat /proc/$(pidof camera)/status`
– `strace -p $(pidof camera)`
– `watch -n 1 ‘ls -l /dev/camera’`
– `grep -r “pthread_” /system/lib/`
– `logcat | grep -i race`
How Exploit:
- Local high-privilege access required.
- Trigger simultaneous thread operations.
- Exploit timing windows in camera functions.
- Cause resource contention or crashes.
Protection from this CVE
- Apply Huawei security updates.
- Restrict local high privileges.
- Implement thread synchronization fixes.
- Monitor camera module logs.
Impact:
- Availability disruption (high).
- Integrity compromise (low).
- Camera service denial.
