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