Important: kernel
Issue Overview: An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access to MMIO registers. Incorrect access checking in the VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses could lead to arbitrary write access to kern...
AMD INVD Instruction Security Notice
Bulletin ID: AMD-SB-3005 Potential Impact: Memory integrity Severity: Medium Summary External researchers reported a potential vulnerability with the INVD instruction that may lead to a loss of SEV-ES and SEV-SNP guest virtual machine VM memory integrity. CVE Details Refer to Glossary for...
An issue was discovered in the Linux kernel before 6.5.9 exploitable by local users with userspace access to MMIO registers. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege escalation). This depends on a race condition through which userspace can replace an instruction before the #VC handler reads it.

CVE-2023-4155 Sev-es / sev-snp vmgexit double fetch vulnerability
A flaw was found in KVM AMD Secure Encrypted Virtualization SEV in the Linux kernel. A KVM guest using 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 multiple time...
