NVD Description

Note: Versions mentioned in the description apply only to the upstream php:8.2/php-soap package and not the php:8.2/php-soap package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

In PHP versions:8.1.* before 8.1.33, 8.2.* before 8.2.29, 8.3.* before 8.3.23, 8.4.* before 8.4.10 when parsing XML data in SOAP extensions, overly large (>2Gb) XML namespace prefix may lead to null pointer dereference. This may lead to crashes and affect the availability of the target server.
