A flaw was found in MariaDB. An authenticated database user with low privileges can trigger a use-after-free memory corruption condition during cursor FETCH operations involving SYS_REFCURSOR. This flaw allows an attacker to corrupt memory and hijack program execution flow, potentially leading to privilege escalation and arbitrary code execution on the host system or causing a denial of service (DoS) by crashing the database server.
