arc_get_cpu_map() fetches the possible-cpus or present-cpus property from the flat DT and immediately passes the raw pointer to cpulist_parse(). That parser expects a NUL-terminated text buffer, but this path does not prove that the DT property is terminated within its declared bounds. Reject unterminated CPU-map properties before handing them to cpulist_parse(). Changes since v1: - fold the NUL-termination check into the initial lookup test, as suggested by Vineet Gupta Signed-off-by: Pengpeng Hou <pengpeng@iscas.ac.cn> Signed-off-by: Vineet Gupta <vgupta@kernel.org>
