In the Linux kernel, the following vulnerability has been resolved:

USB: hub: Ignore non-compliant devices with too many configs or interfaces

Robert Morris created a test program which can cause usbhubtostructhub() to dereference a NULL or inappropriate pointer:

Oops: general protection fault, probably for non-canonical address 0xcccccccccccccccc: 0000 [#1] SMP DEBUGPAGEALLOC PTI CPU: 7 UID: 0 PID: 117 Comm: kworker/7:1 Not tainted 6.13.0-rc3-00017-gf44d154d6e3d #14 Hardware name: FreeBSD BHYVE/BHYVE, BIOS 14.0 10/17/2021 Workqueue: usbhubwq hubevent RIP: 0010:usbhubadjustdeviceremovable+0x78/0x110 ...

The cause of this error is that the device has two interfaces, and the hub driver binds to interface 1 instead of interface 0, which is where usbhubtostructhub() looks.

We can prevent the problem from occurring by refusing to accept hub devices that violate the USB spec by having more than one configuration or interface.
