Subject: Re: [PATCH v2] kgdb: Fix buffer overflow in the 'M' and 'X' packet handlers
Date: Wed, 23 Sep 2026 18:48:04 +0800	[thread overview]
Message-ID: <f19bdb30-c2db-4c03-a887-e31e1a13101e.fangxy@xiaopeng.com> (raw)
In-Reply-To: <f9f9770d-f3de-4d49-b5b8-7d79dcb2d758.fangxy@xiaopeng.com>

Hi Doug,

One correction to my previous reply: after checking the packet
parsing more closely, I don't think an explicit `ptr > buf_end`
check is needed.

I'll keep the v3 implementation without this redundant check.

Thanks
