DEBIAN-CVE-2020-8834
KVM in the Linux kernel on Power8 processors has a conflicting use of HSTATEHOSTR1 to store r1 state in kvmppchventry plus in kvmppcsave,restoretm, leading to a stack corruption. Because of this, an attacker with the ability run code in kernel space of a guest VM can cause the host kernel to pani...
CVE-2020-8834
A flaw was found in the way the KVM hypervisor on the Power8 processor stores the r1 register state in the 'HSTATEHOSTR1' field on the Linux kernel stack. This flaw occurs while handling hypercalls in Transactional Memory TM suspend mode in the kvmppcsavetm and kvmppcrestoretm routines, leading t...
Kernel: KVM: leak of uninitialized stack contents to guest
An information leakage issue was found in the way Linux kernel's KVM hypervisor handled page fault exceptions while emulating instructions like VMXON, VMCLEAR, VMPTRLD, and VMWRITE with memory address as an operand. It occurs if the operand is a mmio address, as the returned exception object hold...
Information Disclosure
QEMU is vulnerable to information disclosure attacks. This is because the patchinstruction function in hw/i386/kvmvapic.c does not initialize the imm32 variable which allows a local attacker to obtain sensitive information from host stack memory by accessing the Task Priority Register TPR...
