Descriptions

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vkms: fix a possible null pointer dereference In amdgpu_vkms_conn_get_modes(), the return value of drm_cvt_mode()
is assigned to mode, which will lead to a NULL pointer dereference
on failure of drm_cvt_mode(). Add a check to avoid null pointer
dereference.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amdgpu/vkms: soluciona una posible desreferencia del puntero null. En amdgpu_vkms_conn_get_modes(), el valor de retorno de drm_cvt_mode() se asigna al modo, lo que provocará una desreferencia del puntero NULL en falla de drm_cvt_mode(). Agregue una marca para evitar la desreferencia del puntero null.
