title: Out of bound read in elf_note_prpsinfo()
description: When dumping core and saving process information, proc_getargv() might return an sbuf which have a sbuf_len() of 0 or -1, which is not properly handled.
An out-of-bound read can happen when user constructs a specially crafted ps_string, which in turn can cause the kernel to crash.
