**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A race condition exists in the Linux kernel's V3D driver, specifically in the `drm/v3d` component. This condition occurs when the job pointer is assigned to NULL before signaling the fence, leading to a potential NULL pointer dereference. The issue arises from the interaction between the DRM scheduler workqueue and the IRQ execution thread. When a new job is executed and the fence is signaled, the IRQ execution thread may set the job pointer to NULL simultaneously with the `run job()` function assigning a new job to the pointer. This can cause a crash when the new job completes and the GPU emits an interrupt, triggering the `v3d irq()` function. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
