Subject: [PATCH v1 0/1] Add buffer size check before save state read
Date: Fri, 26 Mar 2021 16:41:41 -0700 [thread overview]
Message-ID: <20210326234142.1973-1-kuqin12@gmail.com> (raw)
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3283
This change added buffer width check before copying IO information into
incoming buffer. This bug could potentially corrupt memory due to out of
buffer boundary memory access.
Patch v1 branch: https://github.com/kuqin12/edk2/tree/svst_width_v1
