Descriptions

In the Linux kernel, the following vulnerability has been resolved:

drm/panel: fix a possible null pointer dereference

In versatile_panel_get_modes(), the return value of drm_mode_duplicate()
is assigned to mode, which will lead to a NULL pointer dereference
on failure of drm_mode_duplicate(). Add a check to avoid npd.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/panel: corrige una posible desreferencia del puntero null. En versatile_panel_get_modes(), el valor de retorno de drm_mode_duplicate() se asigna al modo, lo que conducirá a una desreferencia del puntero NULL en caso de falla de drm_mode_duplicate(). Agregue una marca para evitar npd.
