Medium: kernel

Issue Overview: A stack buffer overflow issue was found in the getrawsocket routine of the Host kernel accelerator for virtio net vhost-net driver. It could occur while doing an ictolVHOSTNETSETBACKEND call, and retrieving socket name in a kernel stack variable via getrawsocket. A user able to...

CVE-2019-14821

An out-of-bounds access issue was found in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvmcoalescedmmio' object, wherein write indices 'ring-first' and 'ring-last' value could be supplied by a host user-space...

DEBIAN-CVE-2020-2732

A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into accessing sensitive L1 resources that should be inaccessible to the L2 guest...
