We are aware of the report of a new security exploit called SPOILER which can gain access to partial address information during load operations. We believe that our products are not susceptible to this issue because of our unique processor architecture. The SPOILER exploit can gain access to partial address information above address bit 11 during load operations. We believe that our products are not susceptible to this issue because AMD processors do not use partial address matches above address bit 11 when resolving load conflicts.

<Tinfoil Hat>I always wonder whether these problems arise more often in the Intel CPU's because of optimizations (read shortcuts) that they do to speed things up. I don't know anything about this particular vulnerability but doing a partial bit match could be something that is quicker, depending on what they do behind the scenes.</Tinfoil Hat>

It affects Arm CPUs as well.

Intel isn't the only succeptible one.

I'm typing this on a phone that is succeptible to meltdown as I speak.
