I think it's the lockdown patches that have failed. They did the wrong thing, they didn't work,
The report in question is for a regression.
THERE ARE NO VALID ARGUMENTS FOR REGRESSIONS.
Honestly, security people need to understand that "not working" is not a success case of security. It's a failure case.
Yes, "not working" may be secure. But security in that case is *pointless*.
