Recently, Linux users have been warned that the Dirty COW flaw can allow hackers to easily invade and gain full access to a system. While this vulnerability has been around since 2007, it has only been discovered and manipulated recently.

Dirty COW is definitely something to worry about for most Linux systems. As Phil Oester, the programmer to discover it, has said:

“The exploit in the wild is trivial to execute, never fails and has probably been around for years – the version I obtained was compiled with gcc 4.8. As Linus [Torvalds] notes in his commit, this is an ancient bug and impacts kernels going back many years. All Linux users need to take this bug very seriously, and patch their systems ASAP.”

But do you need to worry about this vulnerability affecting your Comrex systems? The short answer is, not at all. A hacker exploiting this flaw would use it to elevate their privileges in a system, to take control of the affected device. Comrex devices do not provide any user escalation capability at all, and so they are not vulnerable.

Even so, it’s good to be aware and protect your other systems! The kernel has already been fixed, and organizations are currently prepping security patches, so keep your firmware up to date.
