Subject: Re: [Linux-kernel-mentees] [PATCH] media/v4l2-core: Fix kernel-infoleak in video_put_user()
Date: Sun, 26 Jul 2020 14:12:22 -0400	[thread overview]
Message-ID: <20200726181222.GB49356@PWN> (raw)
In-Reply-To: <20200726173044.GA14755@pendragon.ideasonboard.com>

Sorry, by this code example:

        char *p = (char *)&vb32;
        int i;

        for (i = 0; i < sizeof(struct vb32); i++, p++)
                printk("*(p + i): %d", *(p + i));

actually I meant:

        char *p = (char *)&vb32;
        int i;

        for (i = 0; i < sizeof(struct vb32); i++)
                printk("*(p + i): %d", *(p + i));

But the idea is the same.

Thank you,
Peilin Ye
