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.

Executive Summary

This vulnerability occurs in the Linux kernel's media component for Mediatek's vcodec. When a late decode error happens, the core thread attempts to set the destination buffer as done by calling v4l2_m2m_buf_done. However, if the lat architecture calls v4l2_m2m_buf_done_and_job_finish to free the destination buffer during a decode error, the core thread may access a NULL pointer in the kernel, causing a crash.

Impact Analysis

This vulnerability can cause the Linux kernel to crash due to a NULL pointer dereference when handling decode errors in the Mediatek vcodec media component. Such crashes can lead to system instability, denial of service, or unexpected reboots.
