Astra Linux – Vulnerability in amd64-microcode

Secure Encrypted Virtualization SEV on the Advanced Micro Devices AMD Platform Security Processor PSP; also known as AMD Secure Processor or AMD-SP 0.17 build 11 and earlier has an insecure cryptographic implementation...

Astra Linux – Vulnerability in Linux 5.15

A flaw was discovered in KVM AMD Secure Encrypted Virtualization SEV within the Linux kernel. A KVM guest that uses SEV-ES or SEV-SNP with multiple vCPUs can trigger a double fetch race condition vulnerability and invoke the VMGEXIT handler recursively. If an attacker manages to call the handler...

Astra Linux – Vulnerability in amd64-microcode

Improper signature verification in the AMD CPU ROM microcode patch loader may allow an attacker with local administrator privileges to load malicious CPU microcode, resulting in a loss of confidentiality and integrity for confidential guests running under AMD SEV-SNP...

CVE-2026-64308

A flaw was found in the Linux kernel's crypto: ccp module, which handles AMD Secure Encrypted Virtualization SEV and Secure Nested Paging SNP features. A local user, by sending specific commands through the /dev/sev interface, could exploit improper initialization handling. If SEV initialization...
