Subject: [PATCH v5.10.y 2/2] HID: uhid: Over-ride the default maximum data buffer value with our own
Date: Mon, 20 Mar 2023 13:06:32 +0000 [thread overview]
Message-ID: <20230320130632.2770364-2-lee@kernel.org> (raw)
In-Reply-To: <20230320130632.2770364-1-lee@kernel.org>
commit 1c5d4221240a233df2440fe75c881465cdf8da07 upstream.
The default maximum data buffer size for this interface is UHID_DATA_MAX
(4k). When data buffers are being processed, ensure this value is used
when ensuring the sanity, rather than a value between the user provided
value and HID_MAX_BUFFER_SIZE (16k).
