Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

PHP是PHP开源的一种在服务器端执行的脚本语言。 PHP 8.2.31之前版本、8.3.31之前版本、8.4.21之前版本和8.5.6之前版本存在代码问题漏洞，该漏洞源于当SOAP服务器配置了类型映射时，解码过程中在缺少值元素的情况下检查了错误的变量，导致空指针取消引用造成段错误，远程未认证攻击者可利用此漏洞使PHP SOAP服务器进程崩溃。

Vulnerability Title
NULL pointer dereference in SOAP apache:Map decoder with missing <value>
Source: CVE Program / CVE List V5
Vulnerability Description
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, when a SOAP server has a typemap configured, the decoding process contains a mistake which checks the wrong variable in case of missing value element.  This leads to dereferences a NULL pointer, causing a segmentation fault. This allows a remote unauthenticated attacker to crash the PHP SOAP server process, resulting in denial of service.
