漏洞标题
drm/v3d: 在任务完成后确保任务指针被设置为 NULL
来源：AIGC 神龙大模型
漏洞描述信息
在Linux内核中，已修复以下漏洞： drm/v3d：确保作业完成后将作业指针设置为NULL 在作业完成之后，设备中对应的指针必须被设置为NULL。如果不这样做，在卸载驱动程序时会触发警告，因为看起来作业仍然处于活动状态。为了避免这种情况，在完成作业后将作业指针设置为NULL，以表明作业已经结束。

漏洞标题
drm/v3d: Ensure job pointer is set to NULL after job completion
来源：美国国家漏洞数据库 NVD
漏洞描述信息
In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Ensure job pointer is set to NULL after job completion After a job completes, the corresponding pointer in the device must be set to NULL. Failing to do so triggers a warning when unloading the driver, as it appears the job is still active. To prevent this, assign the job pointer to NULL after completing the job, indicating the job has finished.
