Crash  is a tool for interactively analyzing the state of the Linux system while it is running, or after a kernel crash has occurred and a core dump has been created.

If crash is invoked with a wrong set of arguments, it can consume all available memory and the machine will be unusable until hard  rebootet.

Example for a bad invocation (do NOT use this!):

crash vmlinux- vmlinux- vmcore

Instead a correct command would be:

crash /boot/  vmlinux-  vmcore


Issue is reported to development, release date of a fixed version of the crash utility is unknown at the moment.

See the manpage for crash for further information about how to use it correctly.

man 8 crash

crash versions up to and including at least crash- are affected.
