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&#39;s possible to access unreserved<br />
resources through the export.<br />
<br />
Add a check to the DMABUF-creation path.
