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

usb: core: sysfs: add lock to bos_descriptors_read()

Add a lock to the function bos_descriptors_read().

This function accesses udev->bos, which could be simultaneously freed in usb_reset_and_verify_device(), a function that is commonly called in drivers all over the kernel.
