+Subject: [PATCH] hw/usb/core.c fix buffer overflow
+
+Store calculated setup_len in a local variable, verify it,
+ and only write it to the struct (USBDevice->setup_len) in case it passed the
+ sanity checks.
+
+This prevents other code (do_token_{in,out} function specifically)
+from working with invalid USBDevice->setup_len values and overruning
+the USBDevice->setup_buf[] buffer.
+Store
+Fixes: CVE-2020-14364
+Signed-off-by: Gred Hoffman <kraxel@redhat.com>
