I assume it affects Jessie as well since it is a fundamental issue JavaScript on arm64. The JS engine provides 47 bits of JSValue for the virtual address space while arm64 requires 48 bits. Looking at the patch upstream [1], you can see that the issue with address bits being used by the JS engine affects many architectures. It's definitely a good idea to backport this.
