It was discovered that the Traffic-Control Index TCINDEX implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2023-1281 It was discovered that the KVM VMX...

SUSE CVE-2013-2212

The vmxsetucmode function in Xen 3.3 through 4.3, when disabling caches, allows local HVM guests with access to memory mapped I/O regions to cause a denial of service CPU consumption and possibly hypervisor or guest kernel panic via a crafted GFN range...

SUSE CVE-2016-2271

VMX in Xen 4.6.x and earlier, when using an Intel or Cyrix CPU, allows local HVM guest users to cause a denial of service guest crash via vectors related to a non-canonical RIP...

SUSE CVE-2017-8106

The handleinvept function in arch/x86/kvm/vmx.c in the Linux kernel 3.12 through 3.15 allows privileged KVM guest OS users to cause a denial of service NULL pointer dereference and host OS crash via a single-context INVEPT instruction with a NULL EPT pointer...

CVE-2022-2196 Speculative execution attacks in KVM VMX

A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM L0 advertising eIBRS support to L1. An attacker at L2 with code...
