Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mshv: Fix create memory region overlap check<br /> <br /> The current check is incorrect; it only checks if the beginning or end<br /> of a region is within an existing region. This doesn&amp;#39;t account for<br /> userspace specifying a region that begins before and ends after an<br /> existing region.<br /> <br /> Change the logic to a range intersection check against gfns and uaddrs<br /> for each region.<br /> <br /> Remove mshv_partition_region_by_uaddr() as it is no longer used.
