Description Adam Mariš 2016-03-31 09:20:24 UTC 
It was found that EINJ, error injection mechanism, is allowed even if securelevel, a prevention from userspace performing actions that undermine trust in the platform, is enabled. This can have undesirable side-effects, such as causing the platform to mark hardware as needing replacement.
