Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> vfio/pci: Check BAR resources before exporting a DMABUF<br /> <br /> A DMABUF exports access to BAR resources and, although they are<br /> requested at startup time, we need to ensure they really were reserved<br /> before exporting. Otherwise, it&amp;#39;s possible to access unreserved<br /> resources through the export.<br /> <br /> Add a check to the DMABUF-creation path.
