CVE-2026-85745

MEDIUM 4.3

Published 2026-10-16 · Last modified 2026-10-19

MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, ST_Area reads beyond the allocated buffer when processing invalid WKB for a MultiPolygon because the multi-polygon parser advances past a nested geometry header without first verifying enough input remains. A low-privileged remote attacker can supply malformed spatial data to disclose memory useful for bypassing ASLR as part of a multi-vulnerability chain. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.

    • vendor fix: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Vendor guidance
    • workaround: Restrict network access to the MariaDB service so that only trusted client systems or the local host can connect. 1. If the database is only accessed locally, configure MariaDB to listen exclusively on localhost by editing `/etc/my.cnf.d/mariadb-server.cnf` under the `[mysqld]` section: ``` bind-address = 127.0.0.1 ``` Then restart the MariaDB service: ``` systemctl restart mariadb ``` 2. If remote access is necessary, use firewalld to block untrusted networks and permit access only from designated IP addresses or subnets: ``` firewall-cmd --permanent --remove-service=mariadb firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="192.168.1.0/24" service name="mariadb" accept' firewall-cmd --reload ``` Caveats: Restricting network reachability limits exposure to authorized networks and prevents untrusted network users from connecting, but it does not protect against malicious queries executed by already authenticated database accounts on permitted networks. Warning: Modifying firewall rules or binding addresses requires reloading firewall configurations or restarting the MariaDB service, which will terminate existing database connections and disrupt active services.

    • workaround: Restrict network access to the MariaDB service so that only trusted client systems or the local host can connect. 1. If the database is only accessed locally, configure MariaDB to listen exclusively on localhost by editing `/etc/my.cnf.d/mariadb-server.cnf` under the `[mysqld]` section: ``` bind-address = 127.0.0.1 ``` Then restart the MariaDB service: ``` systemctl restart mariadb ``` 2. If remote access is necessary, use firewalld to block untrusted networks and permit access only from designated IP addresses or subnets: ``` firewall-cmd --permanent --remove-service=mariadb firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="192.168.1.0/24" service name="mariadb" accept' firewall-cmd --reload ``` Caveats: Restricting network reachability limits exposure to authorized networks and prevents untrusted network users from connecting, but it does not protect against malicious queries executed by already authenticated database accounts on permitted networks. Warning: Modifying firewall rules or binding addresses requires reloading firewall configurations or restarting the MariaDB service, which will terminate existing database connections and disrupt active services.
