Just read this on full disclosure:


Is it valid?  No working proof of concept code has been posted so I can't
test my systems.  The article only lists 2.4 and 2.6.  Is this
2.4.16-current, etc?  Anyone have any details about versions that are
safe so I/We can determine if I need to roll a new production kernel out

It is possible that the problem is exploitable. There is no known public
exploit yet, however.

2.4.24 includes a fix for this (mm/mremap.c diff)
