Description (English)

Linux Kernel is the kernel used by Linux, the Open Source Operator System of the Linux Foundation of the United States. Linux Kernel has a security loophole, which stems from the fact that the propagate mnt function does not terminate the search at the same node of the source mounted tree during the processing of the mount dissemination, which may lead to the loss of the empty pointer.
