An unsigned integer underflow vulnerability in IPA driver result into a buffer over-read while reading NAT entry using debugfs command 'cat /sys/kernel/debug/ipa/ip4_nat'
The product reads from a buffer using buffer access mechanisms such as indexes or pointers that reference memory locations after the targeted buffer.
The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
