CVE-2025-68743: Linux

EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux: from 6.15, before 6.17.13 (fixed in 6.17.13); from 6.18, before 6.18.2 (fixed in 6.18.2)
