Summary

Reference counting in php_request_shutdown causes Use-After-Free

Details

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.
