Description OSIDB Bzimport 2025-01-15 14:03:49 UTC

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.
