Resource exhaustion in Quickjs Project

CVE-2025-69654

A crafted JavaScript input executed with the QuickJS release 2025-09-13, fixed in commit fcd33c1afa7b3028531f53cd1190a3877454f6b3 (2025-12-11),`qjs` interpreter using the `-m` option and a low memory limit can cause an out-of-memory condition followed by an assertion failure in JS_FreeRuntime (list_empty(&rt->gc_obj_list)) during runtime cleanup. Although the engine reports an OOM error, it subsequently aborts with SIGABRT because the GC object list is not fully released. This results in a denial of service.
