Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/shmem_helper: Check VMA boundaries for PMD mappings<br />
<br />
In the ->huge_fault handler do not install a PMD huge page<br />
mapping if the huge page exceeds the boundaries of the VMA.<br />
<br />
All other ->huge_fault handlers have similar checks and the<br />
resulting mapping will trigger a VM_BUG_ON_VMA() if it ever<br />
reaches copy_pmd_range().
