From 5dee7f0b0233f8b4e43e1212a6a96cdee835a8e6 Mon Sep 17 00:00:00 2001 From: Ye Li Date: Tue, 18 Aug 2020 18:16:45 +0800 Subject: [PATCH] f_sdp: Fix wrong usb request size Because the buffer length of sdp usb request is 65, we have to allocate 65 bytes not 64 bytes. Otherwise there is potential buffer overflow.
