+# <a name="InitParser"></a> Fuzzer for InitParser
+
+InitParser supports the following parameters:
+1. ValidPathNames (parameter name: "kValidPaths")
+2. ValidParseInputs (parameter name: "kValidInputs")
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+|`kValidPaths`| 0.`/system/etc/init/hw/init.rc`,<br/> 1.`/system/etc/init` |Value obtained from FuzzedDataProvider|
+|`kValidInputs`| 0.`{"","cpu", "10", "10"}`,<br/> 1.`{"","RLIM_CPU", "10", "10"}`,<br/> 2.`{"","12", "unlimited", "10"}`,<br/> 3.`{"","13", "-1", "10"}`,<br/> 4.`{"","14", "10", "unlimited"}`,<br/> 5.`{"","15", "10", "-1"}` |Value obtained from FuzzedDataProvider|
+
+#### Steps to run
+1. Build the fuzzer
+```
+  $ mm -j$(nproc) init_parser_fuzzer
+```
+2. Run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/init_parser_fuzzer/init_parser_fuzzer
+```
