DEBIAN-CVE-2020-36311
An issue was discovered in the Linux kernel before 5.9. arch/x86/kvm/svm/sev.c allows attackers to cause a denial of service soft lockup by triggering destruction of a large SEV VM which requires unregistering many encrypted regions, aka CID-7be74942f184...
MGASA-2019-0207 Updated microcode package fixes security vulnerability
Secure Encrypted Virtualization SEV on Advanced Micro DevicesAMD Platform Security Processor PSP; aka AMD Secure Processor or AMD-SP 0.17 build 11 and earlier has an insecure cryptographic implementation. This update provides Amd SEV Firmware to 0.17 build 22 CVE-2019-9836. It also updates the...
AMD Secure Encrypted Virtualization (SEV) Key Recovery Vulnerability
AMD Secure Encrypted Virtualization SEV is a hardware memory encryption feature. SEV protects guest virtual machines from the hypervisor, provides confidentiality guarantees at runtime and remote attestation at launch time. The SEV elliptic-curve ECC implementation was found to be vulnerable to a...

SEVered Attack Extracts the Memory of AMD-Encrypted VMs
UPDATE Virtual machines that use AMD’s Secure Encrypted Virtualization SEV, a hardware-based encryption scheme, have been found to be vulnerable to the same malicious hypervisor attacks that can affect all processors. A successful attack can extract the full contents of their main memory in...
Researchers Defeat AMD's SEV Virtual Machine Encryption
German security researchers claim to have found a new practical attack against virtual machines VMs protected using AMD's Secure Encrypted Virtualization SEV technology that could allow attackers to recover plaintext memory data from guest VMs. AMD's Secure Encrypted Virtualization SEV technology...
