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...

QEMU: improper IDE controller reset can lead to MBR overwrite

A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead potentially overwriting the VM's boot code. This could be used, for example, by L2 guests with a virtual disk vdiskL2 stored on a virtual disk of an L1 vdiskL1...

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...
