Subject: Re: [PATCH 1/2 net] NFC: nci: Add some bounds checking in

From: Dan Carpenter <>
Date: Wed, 3 Apr 2019 10:12:48 +0300

> This is similar to commit 674d9de02aa7 ("NFC: Fix possible memory
> corruption when handling SHDLC I-Frame commands").
> I'm not totally sure, but I think that commit description may have

> Anyway, these days we add bounds checking where ever we can and we call
> it kernel hardening.  Better safe than sorry.
