Subject: [PATCH net] ieee802154: reassembly: fix possible buffer overflow
Date: Sun, 29 Jun 2014 13:10:18 +0200 [thread overview]
Message-ID: <1404040218-31122-1-git-send-email-alex.aring@gmail.com> (raw)
The max_dsize attribute in ctl_table for lowpan_frags_ns_ctl_table is
configured with integer accessing methods. This patch change the
max_dsize attribute to int to avoid a possible buffer overflow.
