| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmisc/libmasm/module: Fix two use after free in ibmasm_init_one\n\nIn ibmasm_init_one, it calls ibmasm_init_remote_input_dev().\nInside ibmasm_init_remote_input_dev, mouse_dev and keybd_dev are\nallocated by input_allocate_device(), and assigned to\nsp->remote.mouse_dev and sp->remote.keybd_dev respectively.\n\nIn the err_free_devices error branch of ibmasm_init_one,\nmouse_dev and keybd_dev are freed by input_free_device(), and return\nerror. Then the execution runs into error_send_message error branch\nof ibmasm_init_one, where ibmasm_free_remote_input_dev(sp) is called\nto unregister the freed sp->remote.mouse_dev and sp->remote.keybd_dev.\n\nMy patch add a \"error_init_remote\" label to handle the error of\nibmasm_init_remote_input_dev(), to avoid the uaf bugs." |
