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。- HIDappletb-kbd修复 input_handler_list 的内存损坏 在 appletb_kbd_probe 中初始化输入处理程序然后通过 input_register_handler() 向输入内核注册。发生这种情况时输入核心会将输入处理程序特别是其节点添加到全局 input_handler_list。input_handler_list 对于输入 Core 的功能至关重要，会在输入 Core 中的多个位置遍历。此问题的一个示例为插入新的输入设备并在输入核心中注册。探测中的 input_handler 作为设备管理的内存进行分配。如果 input_register_handler() 之后发生探测失败 input_handler 内存将释放但仍会保留在 input_handler_list 中。
这实际上意味着 input_handler_list 包含指向属于已释放输入处理程序的数据的悬摆指针。这会在插入任何其他输入设备时造成问题 - 就我而言，我有一个旧的 PixArt HP USB 光学鼠标，在 input_register_handler() 后发生失败后，我决定将其插入。这导致通过 input_register_device 注册此输入设备涉及遍历已损坏 input_handler_list 中的每个处理程序以及调用 input_attach_handler()从而使每个处理程序都有机会绑定到新注册的设备。此缺陷的核心是 UAF 会导致 input_handler_list 的内存损坏为了修复此问题我们必须确保从输入核心取消注册输入处理程序这是通过 input_unregister_handler() 完成的。 [ 63.191597] ============================================== ==================== [ 63.192094] BUGKASANinput_attach_handler.isra.0+0x1a9/0x1e0 中的 slab-use-after-free [ 63.192094] Read地址 ffff888105ea7c80 中大小为 8 的漏洞由任务 kworker/0:2/54 [ 63.192094] [ 63.192094] CPU: 0 UID: 0 PID: 54 Comm: kworker/0:2 未受感染 6.16.0-rc2-00321-g2aa6621d [ 63.192094] 硬件名称QEMU Standard PC (i440FX + PIIX,1996), BIOS 1.16.2-debian-1.164 [ 63.192094] 工作队列usb_hub_wq hub_event [ 63.192094] 调用跟踪[ 63.192094] <TASK> [ 63.192094] dump_stack_lvl +0x53/0x70 [ 63.192094] print_report+0xce/0x670 [ 63.192094] kasan_report+0xce/0x100 [ 63.192094] input_attach_handler.isra.0+0x1a9/0x1e0 [ 63.192094] input_register_device+0x76c/0xd00 [ 63.192094] hidinput_connect+ 0x686d/0xad60 [ 63.192094] hid_connect+0xf20/0x1b10 [ 63.192094] hid_hw_start+0x83/0x100 [ 63.192094] hid_device_probe+0x2d1/0x680 [63.192094] real_probe+0x1c3/0x690 [ 63.192094] __driver_probe_device+0x247/0x3000[ 63.192094] ] driver_probe_device+0x49/0x210 [ 63.192094] __device_attach_driver+0x160/0x320 [ 63.192094] bus_for_each_drv+0x10f/0x190 [ 63.192094] __device_a ttach+0x18e/0x370 [ 63.192094] bus_probe_device+0x123/0x170 [ 63.192094] device_add+0xd4d/0x1460 [ 63.192094] hid_add_device+0x30b/0x910 [ 63.192094] usbhid_probe+0x920/0xe00 [ 63.192094] usb_probe_interface+0x9363/0x9363/0x9360 [ 63.192094] real_probe+0x1c3/0x690 [ 63.192094] __driver_probe_device+0x247/0x300 [ 63.192094] driver_probe_device+0x49/0x210 [ 63.192094] __device_attach_driver+0x160/0x320 [ 63.192094] bus_for_each_drv+0x10f/0x190 [ 63.192094] __device_attach +0x18e/0x370 [ 63.192094] bus_probe_device+0x123/0x170 [ 63.192094] device_add+0xd4d/0x1460 [ 63.192094] usb_set_configuration+0xd14/0x1880 [ 63.192094] usb_generic_driver_probe+0x78/0xb0 [ 63.192094] usb_probe_device+0xaa/0x2e0 [ 63.192094] real_probe+0x1c3/0x690 [ 63.192094]
