Subject: [kernel-hardening] Use-after-free and management of reference counts
Date: Tue, 18 Oct 2016 17:52:46 +0530	[thread overview]
Message-ID: <58061416.7020209@oracle.com> (raw)

Hi,

Recently I studied the reported CVEs of last 2 years and there were
fair number of use-after-free bugs. Usually we also see many reports
of use-after-free bugs in the LKML [reported by one or other tools].

Also, at Kernel recipes Jonathan Corbet  mentioned reference counts as
a security issue. I believe if we have more kernel hardening patches
then we can avoid such bugs. I was wondering if there is some ongoing
work in the both [use-after-free and management of reference counts]
of these areas?

If not, then I would like to work on the same. Any pointers on this
would be appreciated.

Thank you.
