Description
A flaw was found in the USB Host Controller Driver framework in the Linux kernel. The usb_giveback_urb function has a logic loophole in its implementation. Due to the inappropriate judgment condition of the goto statement, the function cannot return under the input of a specific malformed descriptor file, so it falls into an endless loop, resulting in a denial of service.
linux内核中的usb_giveback_urb函数在实现时存在逻辑漏洞,由于goto语句的判断条件不恰当,导致在特定的畸形描述符文件输入下该函数无法返回,陷入在死循环中占用CPU资源,导致拒绝服务攻击
