Linux Kernel Vulnerability in DRM V3D Driver Impacting Device Stability

CVE-2025-21697

Summary

In the Linux kernel, a vulnerability exists in the DRM V3D driver related to the handling of job pointers. Upon job completion, the driver fails to set the corresponding pointer to NULL, resulting in misleading warnings during driver unloading that suggest the job is still active. This oversight can lead to stability issues within the device, as improper job state management may cause unforeseen behavior or crashes. To enhance device reliability, it is essential to ensure that the job pointer is properly nullified following job completion.
