It all depends on what gets used for the dynamic loader on a running process. execve() should be fine, the kernel would load the newer, fixed dynamic linker anyway.
And if your environment is currently safe, only applications that allow changing it and which do something weird in userspace with a cached copy of ld.so might need a restart. Maybe dlopen()?
