Upgrade Ubuntu:26.10 php8.5 to version 8.5.9-0ubuntu2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php8.5 package and not the php8.5 package as distributed by Ubuntu. See How to fix? for Ubuntu:26.10 relevant fixed versions and status.

The SOAP HTTP client guards its response buffer growth with a check that relies on signed integer overflow, which is undefined behaviour and is not guaranteed to trigger. When the check is optimised away, a malicious SOAP server can make the client allocate a buffer far smaller than the data it then writes into it, producing a heap buffer overflow.
