Comment 2 Linus Walleij 2019-11-08 14:52:53 UTC
This CVE-numbered bug, i.e. that someone took the trouble to create a CVE for an emulator
of old computer music AdLib/AdPlug, is an excellent example of the disease seen by
kernel maintainer Greg Kroah-Hartmann in the linked article:

https://lwn.net/Articles/801157/

Has anyone made a *serious* threat evaluation of this bug?

Please tell me off for waiving the CVE bug as bogus so I can learn a lesson from this.
