Description Adam Mariš 2018-06-07 16:04:37 UTC

Multiple race condition errors when handling probe, disconnect, and rebind operations can be exploited to trigger a use-after-free condition or a NULL pointer dereference by sending multiple USB over IP packets. Successful exploitation requires USB over IP daemon (usbipd) to be running.

Note:

Currently no Red Hat products are enabling USB-over-IP subsystem, thus no Red Hat products are vulnerable to these flaws.
