How to fix?

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

NVD Description

Note: Versions mentioned in the description apply only to the upstream php-8.2-iconv package and not the php-8.2-iconv 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, the SOAP extension's object deduplication mechanism stores pointers to PHP objects in a global map without incrementing their reference counts. When an apache:Map node contains duplicate keys, processing the second entry overwrites the first in the temporary result map, freeing the original PHP object while its stale pointer remains in the map. A subsequent href reference to the freed node can copy the dangling pointer into the result. As PHP string allocations can reclaim the freed memory region, an attacker with control over the SOAP request body can exploit this use-after-free to achieve remote code execution.
