Hi Salvatore,I've been wondering whether the recent ptrace bug (https://seclists.org/oss-sec/2026/q2/529?) would be exploitable with the default kernel.yama.ptrace_scope=1 – and yes, it still is.
Setting it to 2 seems to prevent it, though.
(After typing this email, I saw that you also had this idea, but I figured it might be helpful to have this information in this thread.)
Cheers, Niklas
