kernel: KVM: 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...

Linux SEV-SNP SEV-ES Data Compromise

The vulnerability of the SEV-SNP and SEV-ES mechanisms in Linux operating systems stems from incorrect neutralization of special elements in the output data used by the incoming component. Exploiting this vulnerability allows an attacker to compromise the confidentiality and integrity of the...

hw: amd: INVD instruction may lead to a loss of SEV-ES guest machine memory integrity problem

A flaw was found in some of AMD CPU's due to improper or unexpected behavior of the INVD. This issue may allow an attacker with a malicious hypervisor to affect cache line write-back behavior of the CPU, potentially leading to a loss of guest virtual machine VM memory integrity...

A vulnerability was found in AMD SEV-SNP, where a malicious hypervisor can potentially break confidentiality and integrity of SEV-SNP on Linux guests by injecting interrupts. An attacker can inject interrupt 0x80, which is used by Linux for legacy 32-bit system calls, and arbitrarily change the...

DEBIAN-CVE-2021-47389

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: fix missing sevdecommission in sevreceivestart DECOMMISSION the current SEV context if binding an ASID fails after RECEIVESTART. Per AMD's SEV API, RECEIVESTART generates a new guest context and thus needs to be paired...

DEBIAN-CVE-2021-47228

In the Linux kernel, the following vulnerability has been resolved: x86/ioremap: Map EFI-reserved memory as encrypted for SEV Some drivers require memory that is marked as EFI boot services data. In order for this memory to not be re-used by the kernel after ExitBootServices, efimemreserve is use...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a lack of DECOMMISSION that may cause subsequent SEV boot failures...

UBUNTU-CVE-2024-25743

In the Linux kernel through 6.9, an untrusted hypervisor can inject virtual interrupts 0 and 14 at any point in time and can trigger the SIGFPE signal handler in userspace applications. This affects AMD SEV-SNP and AMD SEV-ES...
