[edk2-devel] [PATCH v1 0/1] Add buffer size check before save state read

Posted by Kun Qin 3 years ago

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.
