-Subject: [PATCH] usb: limit combined packets to 1 MiB (CVE-2021-3527)
-
-usb-host and usb-redirect try to batch bulk transfers by combining many
-small usb packets into a single, large transfer request, to reduce the
-overhead and improve performance.
-
-This patch adds a size limit of 1 MiB for those combined packets to
-restrict the host resources the guest can bind that way.
