 - Hardware Monitor: Fixed several memory leaks in case hash-file writing (caused by --remove) failed
 - Hardware Monitor: Fixed several memory leaks in case no hardware monitor sensor is found
 - Hardware Monitor: In case NVML initialization failed, do not try to initialiaze NVAPI or XNVCTRL because they both depend on NVML
+- Hardware Management: Bring back kernel exec timeout detection for NVidia on user request
 - Hash Parsing: Added additional bound checks for the SIP digest authentication (MD5) parser (-m 11400)
 - Hash Parsing: Make sure that all files are correctly closed whenever a hash file parsing error occurs
 - Helper: Added functions to check existence, type, read- and write-permissions and rewrite sources to use them instead of stat()
