Critical flaws have been ironed out of the latest version of the open source Linux operating system code, according to software quality experts Coverity.
The clean bill of health comes after an analysis six months ago found six potentially critical defects in the core filesystem and networking code of Linux kernel 2.6.9 – the version used in Red Hat Enterprise Linux 4.0.
Coverity’s analysis of the newest version, Linux kernel 2.6.12, found that the critical defects had all been fixed.
The study examined approximately six million lines of software code from the main Linux kernel, which is the basis for products from vendors such as Red Hat and Novell.
Coverity chief executive Seth Hallem said, “Although the size of the Linux kernel increased over the six month study, we noticed a significant decrease in the number of potentially serious defects in the core Linux kernel.”
He added, “Although contributors introduced new defects, these were primarily in non-critical device drivers."
