CVE-2022-22893Public exploit

Process crash via recursive constructor calls

Published Jan 20, 2022 · Updated Aug 3, 2024

Stack overflow in JerryScript 3.0.0 allows local users to crash an embedding process by executing crafted JavaScript. The vm_loop interpreter path repeatedly constructs a self-recursive function without preventing native call-stack exhaustion. The target must execute attacker-controlled JavaScript; the public test reaches an AddressSanitizer abort, while no stronger consequence is demonstrated.
