CVE-2024-26934 is a deadlock vulnerability in the Linux kernel USB core. The sysfs interface authorization store callback invokes usb_deauthorize_interface(), which acquires the parent USB device lock. If another execution context already holds that lock while removing the interface, such as during a configuration change or device disconnection, removal waits in device_del() for active sysfs callbacks while the callback waits for the parent-device lock. This circular wait prevents both operations from completing. The upstream fix uses sysfs_break_active_protection() so sysfs does not wait for the affected attribute callback during removal.
