+Subject: [PATCH] hw/usb/hcd-uhci: don't assert for SETUP to non-0 endpoint
+
+If the guest feeds invalid data to the UHCI controller, we
+can assert:
+qemu-system-x86_64: ../../hw/usb/core.c:744: usb_ep_get: Assertion `pid == USB_TOKEN_IN || pid == USB_TOKEN_OUT' failed.
+
+(see issue 2548 for the repro case).  This happens because the guest
+attempts USB_TOKEN_SETUP to an endpoint other than 0, which is not
+valid.  The controller code doesn't catch this guest error, so
+instead we hit the assertion in the USB core code.
+
+Catch the case of SETUP to non-zero endpoint, and treat it as a fatal
+error in the TD, in the same way we do for an invalid PID value in
+the TD.
+
+This is the UHCI equivalent of the same bug in OHCI that we fixed in
+commit 3c3c233677 ("hw/usb/hcd-ohci: Fix #1510, #303: pid not IN or
+OUT").
+
+This bug has been tracked as CVE-2024-8354.
