During scanning entire subnet observed errors due to the below list of nasl files in the OS system log:
2021/gb_ssl_tls_ecc_key_224bits.nasl)‘: double free or corruption
2021/gb_ssl_tls_rsa_key_1024bits.nasl)’: double free or corruption
2021/gb_ssl_tls_rsa_key_2048bits.nasl)‘: double free or corruption
2021/gb_ssl_tls_ecc_key_224bits.nasl)’: double free or corruption
Those messages are actually unrelated to the VTs / NASL files and are originating from the underlying scanner executing them (there is no such thing like a double free in NASL unlike e.g. on C) so moving into a better fitting category.
