+Subject: [PATCH] pcnet: force the buffer access to be in bounds during tx
+
+4096 is the maximum length per TMD and it is also currently the size of
+the relay buffer pcnet driver uses for sending the packet data to QEMU
+for further processing. With packet spanning multiple TMDs it can
+happen that the overall packet size will be bigger than sizeof(buffer),
+which results in memory corruption.
+
+Fix this by only allowing to queue maximum sizeof(buffer) bytes.
+
+This is CVE-2015-3209.
+
+[Fixed 3-space indentation to QEMU's 4-space coding standard.
