Comment 13 for bug 959842

BTW: applying the patch will break the CUDA debugger. This is a known issue that will be noted in the public announcement about the vulnerability. The updated driver (295.40) includes additional changes to restore compatibility with the CUDA driver, but applying the patch on its own will break usage.

I'll let you decide which tradeoff you want to make (better security vs. convenience for a relatively small set of users) - users who must use the CUDA debugger will have to choose whether to use an unpatched driver, or an updated one, since a patched but not updated driver will break the CUDA debugger.
