JSON

A vulnerability was found in the Linux kernel, which involves a NULL pointer dereference in the xHCI driver during full-speed USB device enumeration. When a failed address device command occurs, the xhci_virt_device structure is allocated, but its bandwidth table pointers are not properly initialized. This issue leads to a NULL pointer dereference the next time usb_ep0_reinit() is called.

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
