Hi,
I found the CVE-2018-1087 and CVE-2018-8897 should be related to kprobes and uprobes too, since both are using #DB for single stepping.
I decided to just reject probes on MOV SS and POP SS because those are not recommended to use (Intel SDM recommend to use LSS instead), thus it might be rare case.
Oleg, could you review the uprobes patch?
Thank you,
