Security research suggests Linux has fewer flaws.

The conclusion is the result of a four-year research project conducted by code-analysis company Coverity, which plans to release its report on Tuesday. The project found 985 bugs in the 5.7 million lines of code that make up the latest version of the Linux core operating system, or kernel. A typical commercial program of similar size usually has more than 5,000 flaws or defects, according to data from Carnegie Mellon University.
