How remove mariadb built-in function?

Hello,

I want to know how remove or disable mariadb built-in function 'FROM_UNIXTIME'. Since it is a built-in function, we confirmed that it cannot be deleted with the drop function command.

I use mariadb 10.5.15 version. And the reason for requesting deletion of 'FROM_UNIXTIME' is because it is a function with a buffer overflow problem.

Below document is about buffer overflow issue. - https://jira.mariadb.org/browse/MDEV-26422

Please check. And thank you for your quick reply. Thank you.

The issue appears to have been fixed (MDEV-25317), so you could upgrade to a later version.

Short of recompiling yourself, I'm not aware of a way to remove a core function.
