In the Linux kernel, the following vulnerability has been resolved:

usb: yurex: fix race in probe

The bbu member of the descriptor must be set to the value standing for uninitialized values before the URB whose completion handler sets bbu is submitted. Otherwise there is a window during which probing can overwrite already retrieved data.
