Linux Kernel Media: MediaTek VCodec Denial-of-Service Vulnerability in Module Removal

A denial-of-service vulnerability has been identified in the Linux kernel's MediaTek VCodec decoder driver. When the driver is removed, it can cause a kernel crash if the driver supports sub-device mode. This occurs because a certain parameter is null, leading to a crash when the module is unloaded.

Impact

The vulnerability causes a kernel crash, disrupting system operations and potentially leading to a system freeze or reboot.
