A time-of-check time-of-use (TOCTOU) information disclosure vulnerability was found in the Linux Kernel DPT I2O controller. This issue results from the lack of proper locking when performing operations on an object, allowing a privileged local user to escalate privileges and execute arbitrary code in the context of the kernel.
