CVE 描述
In the Linux kernel, the following vulnerability has been resolved:
usb: misc: usbio: check ibuf_len against rxbuf_len in bulk msg
ibuf_len is the bulk IN (receive) buffer size, but the EMSGSIZE check
in usbio_bulk_msg() compares it against txbuf_len — the bulk OUT
endpoint size. Both are taken independently from different endpoints
in usbio_probe(), so the check is wrong when they differ.
Use rxbuf_len for the IN direction. This matches the buffer that
actually holds the response data.
