Zenbleed Begone: MSI Motherboards Roll Out Critical Patch for Ryzen 4000 CPUs

Fear not, MSI motherboard mavens! Your AMD Zen 2 chips are finally getting that security swaddle against Zenbleed attacks. Just snag that BIOS update and wave bye-bye to vulnerability CVE-2023-20593. Gigabyte users, maybe try a rain dance?

Hot Take:

It’s like waiting for your favorite sequel in a movie franchise, except it’s not popcorn you’re clutching, but your digital life. MSI finally rolls out the red carpet for the Zenbleed security patch, and Ryzen 4000 users can now breathe a sigh of relief—or at least those with MSI motherboards can. As for the rest, the suspense continues. Pull up a chair, folks; the Zenbleed saga is getting its patchy ending… eventually.

Key Points:

  • MSI motherboard users with Ryzen 4000 series processors can now update their BIOS with AMD’s AM4 AGESA 1.2.0.Ca to combat the menacing Zenbleed.
  • The BIOS update is a Hollywood-worthy ensemble cast, featuring mitigations against the medium-severity CVE-2023-20593 vulnerability.
  • This patch is the latest fashion, and nearly all MSI X570 motherboards are strutting it, with the B550 and other 500 and 400 series boards joining the runway.
  • There’s a whiff of exclusivity as not all motherboard brands have sent out their invites—looking at you, Gigabyte.
  • Despite the drama, this patch doesn’t cover Ryzen embedded chips, but they’re expecting their own tailored fix any day now.

The Patchwork Chronicles

Once upon a time, in the land of silicon and circuits, there was a delay—a long, drawn-out wait for the knights of AMD to bestow a shield against the Zenbleed dragon. The Ryzen 3000 CPUs got their armor upgraded posthaste, but the Ryzen 4000 series had to hold the fort a little longer. Now, the MSI kingdom has received its arsenal, and the other realms (read: motherboard vendors) are expected to follow suit, lest they fall to the dragon's fiery breath.

Patching the Patchables

MSI's grand gesture is a BIOS update that's like an all-access pass to the "No Zenbleed" club. Nearly every member of the MSI X570 motherboard line has been spotted flaunting this new badge of honor. The B550s and others are on the guest list too, but they might have to wait at the door a bit longer. As for the embedded Ryzen chips, they're the VIPs still waiting for their custom-tailored fix, but rumor has it the tailors are working overtime.

The Waiting Game

Somewhere in the vast expanse of Reddit forums, Gigabyte users are tapping their feet, eyeing the clock, and wondering when their patch limo will arrive. Gigabyte, thus far, seems to be taking a leisurely stroll down Patch Lane. But hope isn't lost, as pressure mounts and users' stares turn into glares, a firmware update is surely on the horizon. After all, who wants to be the last one at the party?

And the Award for Best Security Patch Goes to...

It might not be an Oscar, but in the world of tech, a timely security patch deserves its own red carpet moment. Ryzen 4000 users with MSI motherboards can now update their BIOS scripts and star in their own "No More Zenbleed" feature film. As for the rest of the cast, they're expected to join the ensemble soon. So keep your popcorn ready, but maybe keep that antivirus scanner handy too, just in case.
