 # Description: Embedded kernel exploit matching datasets extracted from linux-exploit-suggester and linux-exploit-suggester-2 examples. Data is split across KERNEL_CVE_DATA_1..X with a maximum of 25 rows per env variable. This file also stores reference-only CVE tokens found in example repos when no explicit suggester matching rule exists.
