CVE-2025-38371 — drm/v3d: Disable interrupts before resetting the GPU

Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

drm/v3d: Disable interrupts before resetting the GPU

Currently, an interrupt can be triggered during a GPU reset, which can lead to GPU hangs and NULL pointer dereference in an interrupt context as shown in the following trace:
