  "details": "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)",
