In the Linux kernel, the following vulnerability has been resolved:
mshv: Fix create memory region overlap check
The current check is incorrect; it only checks if the beginning or end of a region is within an existing region. This doesn't account for userspace specifying a region that begins before and ends after an existing region.
Change the logic to a range intersection check against gfns and uaddrs for each region.
Remove mshv_partition_region_by_uaddr() as it is no longer used.
