hw: amd: Instruction raise #VC exception at exit

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...

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...

kernel: untrusted VMM can trigger int80 syscall handling

A flaw was found in the Linux kernel. A VMM can inject external interrupts on any arbitrary vector at any time, which may allow the guest OS to be manipulated from the VMM side...

kernel: KVM: SVM: Don't BUG if userspace injects an interrupt with GIF=0

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Don't BUG if userspace injects an interrupt with GIF=0 Don't BUG/WARN on interrupt injection due to GIF being cleared, since it's trivial for userspace to force the situation via KVMSETVCPUEVENTS even if having at least...

SUSE CVE-2011-1898

Xen 4.1 before 4.1.1 and 4.0 before 4.0.2, when using PCI passthrough on Intel VT-d chipsets that do not have interrupt remapping, allows guest OS users to gain host OS privileges by "using DMA to generate MSI interrupts by writing to the interrupt injection registers."...

SUSE CVE-2012-5634

Xen 4.2.x, 4.1.x, and 4.0, when using Intel VT-d for PCI passthrough, does not properly configure VT-d when supporting a device that is behind a legacy PCI Bridge, which allows local guests to cause a denial of service to other guests by injecting an interrupt...

SUSE CVE-2017-10919

Xen through 4.8.x mishandles virtual interrupt injection, which allows guest OS users to cause a denial of service hypervisor crash, aka XSA-223...
