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 functionget_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 returnMOD_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)
