CVE-2022-49055 Information

Description

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.
