Doc Type: If docs needed, set a value
Doc Text:
A vulnerability was found in the nfs4_set_security_label() in the Linux kernel, where the function fails to free the nfs_fattr attribute before exiting, leaving said memory allocation present. As the nfs4_set_security_label() is called repeatedly over time, this may lead to memory exhaustion.
