AMD’s Microcode Mishap: When SEVcurity Meets InSECurity!
AMD’s Secure Encrypted Virtualization (SEV) has been hit by a high-severity vulnerability, allowing sneaky attackers with local admin privileges to load malicious CPU microcode. Discovered by Google’s crack team of security sleuths, this flaw could compromise confidential workloads. AMD’s scrambling to patch things up, but it seems SEV isn’t feeling so secure right now.
Hot Take:
Looks like AMD’s SEV has a wee bit of a weak spot. Who knew that the path to compromising security was paved with improperly verified signatures? Someone get those chips some better pens!
Key Points:
- AMD SEV vulnerability (CVE-2024-56161) allows malicious CPU microcode loading.
- Vulnerability carries a high severity CVSS score of 7.2.
- Requires local administrator privileges for exploitation.
- Discovered by Google’s crack team of security researchers.
- Google has released a test payload, but full details are withheld for now.
