In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: Fix potential NULL dereference in mtkcrtcdestroy()
In mtkcrtccreate(), if the call to mboxrequestchannel() fails then we set the "mtkcrtc->cmdqclient.chan" pointer to NULL. In that situation, we do not call cmdqpktcreate().
During the cleanup, we need to check if the "mtkcrtc->cmdqclient.chan" is NULL first before calling cmdqpktdestroy(). Calling cmdqpktdestroy() is unnecessary if we didn't call cmdqpktcreate() and it will result in a NULL pointer dereference.
