Kernelnotes says: “Probably the last 2.0.x release. It fixes a
number of DoS (Denial of Service) vulnerabilities, so it’s probably
worth upgrading.”
Neither kernelnotes.org or
linuxhq.com have any further
details on this patch, so you might as well just download it from
your neighborhood kernel.org mirror. Look in the
/pub/linux/kernel/v2.0 directory.
This kernel is the latest in the 2.0 series, kept for backward
compatibility for those who cannot (or will not) upgrade to the 2.2
series.
