This issue requires that the attacker has logon access to the infrastructure hosting mariadb. The fix for this CVE is also a breaking change for MariaDB and MySQL clients older than version 10.5.25. Considering the tradeoff between the stability of HAQM Linux and the impact and complexity of fixing CVE-2024-21096 will not be provided for mariadb-5.5 in HAQM Linux 2 at this time. If a fix for this CVE is critical to your work, we suggest using mariadb-10.5 in HAQM Linux 2 Extras, which has the fix for CVE-2024-21096.
