The version of MariaDB installed on the remote host is prior to 10.3.26. It is, therefore, affected by multiple vulnerabilities as referenced in the mdb-10326-rn advisory.
Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: FTS). Supported versions that are affected are 5.6.49 and prior, 5.7.31 and prior and 8.0.21 and prior. Easily exploitable vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2020-14765)
Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are affected are 5.7.31 and prior and 8.0.21 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2020-14776)

Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2020-14789)
Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Locking). Supported versions that are affected are 5.6.49 and prior, 5.7.31 and prior and 8.0.21 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2020-14812)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
