This dynamic link library is a component of Sony's SecuROM copy protection software, which protects certain programs (especially games, since they are often pirated) from unauthorized copying. This program is added to the system as part of whatever program is using the SecuROM protection scheme, and is required for that program to run normally. See also UAService7.exe. 

If you want a detailed security rating about your CmdLineExt.dll (and all other running background processes) read the following user opinions, and download the free trial version of Security Task Manager.

Note: Any malware can be named anything - so you should check where the files of the running processes are located on your disk. If a "non-Microsoft" .exe file is located in the C:\Windows or C:\Windows\System32 folder, then there is a high risk for a virus, spyware, trojan or worm infection! Check it out!
