kernel is vulnerable to denial of service (DoS). The Linux kernel’s register set (regset) common infrastructure implementation did not check if the required get and set handlers were initialized, allowing a local, unprivileged user to cause a denial of service by performing a register set operation with a ptrace() PTRACE_SETREGSET or PTRACE_GETREGSET request.
