简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- usb：misc：usbio：修复客户端拆卸中的断开连接 UAF usbio_disconnect（） 反向遍历 usbio->cli_list 并取消初始化每个辅助设备。auxiliary_device_uninit（） 会终止设备引用，并且对于可以运行 usbio_auxdev_release（） 并释放包含的 struct usbio_client的未绑定子项。
list_for_each_entry_reverse（） 通过读取 client->link.prev 在循环正文之后前进。如果 auxiliary_device_uninit（） 释放了当前客户端，迭代器将取消引用释放的内存。使用 list_for_each_entry_safe_reverse（），以便在正文丢弃最终引用之前缓存之前的客户端。这可保留反向拆卸顺序，同时使下一个迭代器光标独立于当前客户端的生命周期。验证重现了此内核报告：缺陷：KASAN：usbio_disconnect+0x12e/0x150 中的释放后使用 slab 调用跟踪： <TASK> dump_stack_lvl+0x66/0xa0 print_report+0xce/0x630 ？ usbio_disconnect+0x12e/0x150 ？ srso_alias_return_thunk+0x5/0xfbef5 ？ __virt_addr_valid+0x188/0x320 ？ usbio_disconnect+0x12e/0x150 kasan_report+0xe0/0x110 ？ usbio_disconnect+0x12e/0x150 usbio_disconnect+0x12e/0x150 usb_unbind_interface+0xf3/0x400 really_probe+0x316/0x660
