Description

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

media: mediatek: vcodec: Can't set dst buffer to done when lat decode error

Core thread will call v4l2_m2m_buf_done to set dst buffer done for lat architecture. If lat call v4l2_m2m_buf_done_and_job_finish to free dst buffer when lat decode error, core thread will access kernel NULL pointer dereference, then crash.
