CVE-2026-64453

A use-after-free in the Linux kernel's usbio USB driver occurs during device disconnection. When usbio_disconnect() iterates the client list in reverse, auxiliary_device_uninit() can free the current struct usbio_client, causing the list_for_each_entry_reverse() iterator to dereference freed memo...
