Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： media: video-i2c：在驱动移除时使用 vb2_video_unregister_device 由于该驱动将其文件释放操作（file release operation）设置为 vb2_fop_release()，因此在移除驱动时，应使用 vb2_video_unregister_device()，而非 video_unregister_device()。 此举可确保在注销视频设备之前，vb2 队列能够被正确断开连接。

Vulnerability Title
media: video-i2c: use vb2_video_unregister_device on driver removal
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: media: video-i2c: use vb2_video_unregister_device on driver removal The driver uses vb2_fop_release() as its file release operation, so vb2_video_unregister_device() should be used instead of video_unregister_device() during driver removal. This ensures that the vb2 queue is properly disconnected before the video device is unregistered.
