Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An issue exists in the usbio bulk msg() function where the ibuf len (bulk IN receive buffer size) is incorrectly compared against txbuf len (bulk OUT endpoint size) during an EMSGSIZE check. Because these values are retrieved from different endpoints in usbio probe(), the check fails when the endpoint sizes differ.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
