In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Check for potential null return of kmalloc_array()
As the kmalloc_array() may return null, the 'event_waiters[i].wait' would lead to null-pointer dereference.
Therefore, it is better to check the return value of kmalloc_array() to avoid this confusion.
