Descriptions

In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/hid/usbhid/hiddev.c driver, aka CID-9c09b214f30e.

En el kernel de Linux versiones anteriores a 5.2.10, se presenta un bug de uso de la memoria previamente liberada que puede ser causado por un dispositivo USB malicioso en el controlador del archivo drivers/hid/usbhid/hiddev.c, también se conoce como CID-9c09b214f30e.

A vulnerability was found in hiddev_open in drivers/hid/usbhid/hiddev.c in the USB Human Interface Device class subsystem, where an existing device must be validated prior to its access. The device should also ensure the hiddev_list cleanup occurs at failure, as this may lead to a use-after-free problem, or possibly escalate privileges to an unauthorized user.

Red Hat CodeReady Workspaces 2.1.0 provides a cloud developer-workspace server and a browser-based IDE built for teams and organizations. CodeReady Workspaces runs in OpenShift and is well-suited for container-based development. Issues addressed include a bypass vulnerability.
