SUSE CVE-2014-3717

Xen 4.4.x does not properly validate the load address for 64-bit ARM guest kernels, which allows local users to read system memory or cause a denial of service crash via a crafted kernel, which triggers a buffer overflow...

SUSE 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...

SUSE CVE-2020-25596

An issue was discovered in Xen through 4.14.x. x86 PV guest kernels can experience denial of service via SYSENTER. The SYSENTER instruction leaves various state sanitization activities to software. One of Xen's sanitization paths injects a GP fault, and incorrectly delivers it twice to the guest...
