Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue concerns the nvmet component in the Linux kernel, where the nvmet root discovery nqn store function treats the subsysnqn string as a fixed-size buffer, despite its dynamic allocation based on the string size. This could potentially lead to a buffer overflow. The resolution involves creating a new string using kstrndup instead of reusing the old buffer.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
