CVE-2024-11235

Publication date 14 March 2025

Last updated 31 March 2025

Ubuntu priority

Medium

Why this priority?

Exception handler frees variables via cleanup_live_vars for termination. However, the subsequent php_request_shutdown performs reference counting on these variables using zend_gc_refcount(read) and zend_gc_delref(write), resulting in use-after-free. Since zend_mm_free_small stores metadata in freed memory chunks, this use-after-free vulnerability may allows manipulation of the Zend allocator through reference count behaviors.
