CVE-2019-19527 is a use-after-free vulnerability in the Linux kernel USB Human Interface Device subsystem, affecting kernels before version 5.2.10. In the hiddev driver's device-open and initialization-failure handling, a race between opening a HID device and device disconnection can remove a list entry while concurrent USB paths retain references to it. A malicious USB device can induce the faulty lifetime-management condition.
