Security group warns of hole in Linux kernel

Computer security researchers are again warning about a critical vulnerability in the Linux kernel that could be used by malicious hackers to take
control of systems using the popular open source operating system.

ISEC Security Research said Monday that it found a critical vulnerability in code that is used to manage virtual memory on Linux systems. The
vulnerability affects versions of the Linux kernel up to and including version 2.6 and would give low-level Linux users total control over a Linux
system.

ISEC, a noncommercial security research group based in Poland, discovered the problem in kernel code for a component called “mremap,” according to a
message posted by Paul Starzetz, an iSEC member.
