How to fix?

Upgrade Minimos:latest php-8.2-mysqlnd-config to version 8.2.31-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php-8.2-mysqlnd-config package and not the php-8.2-mysqlnd-config package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, a mismatch between encoding lists in Oniguruma and mbfl leads to  a NULL pointer dereference, resulting in a segmentation fault and denial of service. The vulnerability is exploitable when user-controlled input can influence the encoding passed to mb_regex_encoding().
