Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw within the
kvaser usb leaf wait cmd() and kvaser usb leaf read bulk callback functions related to handling zero-length commands used for aligning data to USB endpoint boundaries. The driver’s attempt to skip these commands can result in an infinite loop if a zero-length command is found exactly on a packet boundary, because the round up() function returns the unchanged value of pos. This occurs when pos is a multiple of wMaxPacketSize, including 0. The issue is addressed by modifying the calculation to use pos + 1, ensuring that round up() always returns the next aligned boundary.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
