Any further information about this?
Comment 2 Takashi Iwai 2019-07-23 15:03:30 UTC
Also can anyone reproduce the problem on our kernels? I tried it but have never seen Oops.
Comment 3 Robert Frohl 2019-11-18 10:32:55 UTC
Still no new information found concerning this. Will keep it on my todo list.
Comment 4 Takashi Iwai 2020-05-15 11:50:56 UTC
I guess we can close this; the provided PoC never worked on our kernels and i915 devices as far as I've tested, and the influence of this bug is very limited.
Comment 5 Takashi Iwai 2020-05-15 11:51:34 UTC
Reassigned back to security team. If it's still needed to be tracked, please reassign back -- but with more information :)
Comment 6 Robert Frohl 2020-08-25 08:28:11 UTC
just checked again if there was anything new, I think there wont be anything else. Closing
