In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null pointer check in mod_hdcp_hdcp1_create_session()
The function mod_hdcp_hdcp1_create_session() calls the function
get_first_active_display(), but does not check its return value.
The return value is a null pointer if the display list is empty.
This will lead to a null pointer dereference.
Add a null pointer check for get_first_active_display() and return
MOD_HDCP_STATUS_DISPLAY_NOT_FOUND if the function return null.
This is similar to the commit c3e9826a2202
("drm/amd/display: Add null pointer check for get_first_active_display()").
(cherry picked from commit 5e43eb3cd731649c4f8b9134f857be62a416c893)
