UBUNTU-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...
