An integer overflow flaw was found in the Linux kernel’s virtio device driver code in the way a user triggers the vhost_vdpa_config_validate function. This flaw allows a local user to crash or potentially escalate their privileges on the system.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
