AMD on Thursday saw its property drop nearly 4 percent in after-hours trading following a new announcement around how its processors are impacted by a recently disclosed security vulnerability.
On January 3, the chipmaker suggested AMD chips had a near-zero risk of being affected by one variant of the Spectre vulnerability. But on Thursday the allegation said the variant “is applicable” to AMD chips.
“While we believe that AMD’s processor architectures redecorate it difficult to exploit Variant 2, we continue to work closely with the determination on this threat. We have defined additional steps through a conspiracy of processor microcode updates and OS patches that we will make present to AMD customers and partners to further mitigate the threat,” AMD said.
“AMD will attack optional microcode updates available to our customers and partners for Ryzen and EPYC processors starting this week. We surmise to make updates available for our previous generation products over the succeeding weeks.”
The updated statement makes it clear that the Meltdown vulnerability at rest isn’t impacting AMD chips, although it has been affecting Intel’s chips.
AMD pronounced in a statement after this story was initially published that there’s been no replacement to its position on the susceptibility to the second variant of Spectre for its chips and only that it’s float out optional updates to further contain the threat.
Meanwhile, AMD said it has it expects an issue that resulted in pausing the release of some updates take care of against the first variant of the Spectre issue “to be corrected shortly.” Microsoft should be retire b escape those updates out by next week, AMD said.
In a blog post earlier on Thursday, Google contriving vice president Benjamin Treynor Sloss described the Meltdown and About issues as being perhaps the hardest to fix in a decade.
