In the Linux kernel, the following vulnerability has been resolved: staticcall: Replace pointless WARNON() in staticcallmodulenotify() staticcallmodulenotify() triggers a WARNON(), when memory allocation fails in _staticcalladdmodule(). That's not really justified, because the failure case must be correctly handled by the well known call chain and the error code is passed through to the initiating userspace application. A memory allocation fail is not a fatal problem, but the WARNON() takes the machine out when paniconwarn is set. Replace it with a pr_warn().
