AMD on Thursday saw its stock drop nearly 4 percent in after-hours trading following a fresh announcement about how its processors are impacted by a recently disclosed security vulnerability.
On January 3, the chipmaker said AMD chips had a near-zero risk of being affected by one variant of the Spectre vulnerability. although on Thursday the statement said the variant “is usually applicable” to AMD chips.
“While we believe which AMD’s processor architectures make the item difficult to exploit Variant 2, we continue to work closely with the industry on This particular threat. We have defined additional steps through a combination of processor microcode updates along with OS patches which we will make available to AMD customers along with partners to further mitigate the threat,” AMD said.
“AMD will make optional microcode updates available to our customers along with partners for Ryzen along with EPYC processors starting This particular week. We expect to make updates available for our previous generation products over the coming weeks.”
The updated statement makes the item clear which the Meltdown vulnerability still isn’t impacting AMD chips, although the item has been affecting Intel’s chips.
AMD said in a statement after This particular story was initially published which there’s been no change to its position on the susceptibility to the second variant of Spectre for its chips along with only which the item’s rolling out optional updates to further contain the threat.
Meanwhile, AMD said the item expects the item expects an issue which resulted in pausing the Discharge of some updates protecting against the first variant of the Spectre issue “to be corrected shortly.” Microsoft should be getting those updates out by next week, AMD said.
In a blog post earlier on Thursday, Google engineering vice president Benjamin Treynor Sloss described the Meltdown along with Spectre issues as being perhaps the hardest to fix in a decade.
