PTRACE_TRACEME doesn't have proper capabilities validation when parent is less privileged than child. Issue pointed out by Ram Gupta <ram.gupta5@gmail.com>. Note: I haven't identified a strong security issue, and it's a small ABI change that could break apps that rely on existing behaviour (which allows parent that is less privileged than child to ptrace when child does PTRACE_TRACEME).
