High level conclusions

Fuzzer ext2fs_check_directory_fuzzer is blocked:

The runtime code coverage of ext2fs_check_directory_fuzzer covers 7.438% of its statically reachable code. This means there is some place that blocks the fuzzer to continue exploring more code at run time.

Fuzzers reach 21.24% of cyclomatic complexity.

Fuzzers reach 21.23% of all functions.

This section shows which files and directories are considered in this report. The main reason for showing this is fuzz introspector may include more code in the reasoning than is desired. This section helps identify if too many files/directories are included, e.g. third party code, which may be irrelevant for the threat model. In the event too much is included, fuzz introspector supports a configuration file that can exclude data from the report. See the following link for more information on how to create a config file: link
