High level conclusions

Fuzzers reach 66.63% of cyclomatic complexity.

Fuzzers reach 65.25% of all functions.

Fuzzer Tss2_Sys_Create_Complete is blocked:

The runtime code coverage of Tss2_Sys_Create_Complete covers 25.77% of its statically reachable code. This means there is some place that blocks the fuzzer to continue exploring more code at run time.

Fuzzer Tss2_Sys_ReadPublic_Complete is blocked:

The runtime code coverage of Tss2_Sys_ReadPublic_Complete covers 28.73% of its statically reachable code. This means there is some place that blocks the fuzzer to continue exploring more code at run time.

Fuzzer Tss2_Sys_CreatePrimary_Complete is blocked:

The runtime code coverage of Tss2_Sys_CreatePrimary_Complete covers 29.16% of its statically reachable code. This means there is some place that blocks the fuzzer to continue exploring more code at run time.

Fuzzer Tss2_Sys_GetCapability_Complete is blocked:

The runtime code coverage of Tss2_Sys_GetCapability_Complete covers 26.88% of its statically reachable code. This means there is some place that blocks the fuzzer to continue exploring more code at run time.
