-Subject: [PATCH] Drop bogus IPv6 messages
-
-Drop IPv6 message shorter than what's mentioned in the payload
-length header (+ the size of the IPv6 header). They're invalid an could
-lead to data leakage in icmp6_send_echoreply().

+Subject: [PATCH] usb: fix setup_len init (CVE-2020-14364)
+
+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} functions specifically)
+from working with invalid USBDevice->setup_len values and overrunning
+the USBDevice->setup_buf[] buffer.
+
+Fixes: CVE-2020-14364
