How to fix?

Upgrade Alpine:3.22 php83 to version 8.3.18-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php83 package and not the php83 package as distributed by Alpine. See How to fix? for Alpine:3.22 relevant fixed versions and status.

In PHP versions 8.3.* before 8.3.19 and 8.4.* before 8.4.5, a code sequence involving __set handler or ??=  operator and exceptions can lead to a use-after-free vulnerability. If the third party can control the memory layout leading to this, for example by supplying specially crafted inputs to the script, it could lead to remote code execution.
