xhci: Fix Panther point NULL pointer deref at full-speed re-enumeration
来源: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
xhci: Fix Panther point NULL pointer deref at full-speed re-enumeration
re-enumerating full-speed devices after a failed address device command
can trigger a NULL pointer dereference.
Full-speed devices may need to reconfigure the endpoint 0 Max Packet Size
value during enumeration. Usb core calls usb_ep0_reinit() in this case,
which ends up calling xhci_configure_endpoint().
On Panther point xHC the xhci_configure_endpoint() function will
additionally check and reserve bandwidth in software. Other hosts do
this in hardware
If xHC address device command fails then a new xhci_virt_device structure
is allocated as part of re-enabling the slot, but the bandwidth table
pointers are not set up properly here.
This triggers the NULL pointer dereference the next time usb_ep0_reinit()
is called and xhci_configure_endpoint() tries to check and reserve
bandwidth
[46710.713538] usb 3-1: new full-speed USB device number 5 using xhci_hcd
[46710.713699] usb 3-1: Device not responding to setup address.

[46711.125623] Workqueue: usb_hub_wq hub_event [usbcore]
[46711.125668] RIP: 0010:xhci_reserve_bandwidth (drivers/usb/host/xhci.c
Fix this by making sure bandwidth table pointers are set up correctly
after a failed address device command, and additionally by avoiding
checking for bandwidth in cases like this where no actual endpoints are
added or removed, i.e. only context for default control endpoint 0 is
evaluated.
