Description

In the Linux kernel, the following vulnerability has been resolved: nvmet: Don't overflow subsysnqn nvmet_root_discovery_nqn_store treats the subsysnqn string like a fixed size buffer, even though it is dynamically allocated to the size of the string. Create a new string with kstrndup instead of using the old buffer.
