Privilege Escalation

kvm is vulnerable to privilege escalation. The vulnerability exists as a flaw was found in QEMU-KVM, allowing the guest some control over the index used to access the callback array during sub-page MMIO initialization. A privileged guest user could use this flaw to crash the guest denial of servi...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS. The vulnerability exists as a flaw was found in the Memory-mapped I/O MMIO instruction decoder in the Xen hypervisor implementation. An unprivileged guest user could use this flaw to trick the hypervisor into emulating a certain instruction, which...

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...

CVE-2019-0154

A flaw was found in Intel graphics hardware GPU where a local attacker with the ability to issue an ioctl could trigger a hardware level crash if MMIO registers were read while the graphics card was in a low-power state. This creates a denial of service situation and the GPU and connected display...

hw: Intel GPU Denial Of Service while accessing MMIO in lower power state

A flaw was found in Intel graphics hardware GPU where a local attacker with the ability to issue an ioctl could trigger a hardware level crash if MMIO registers were read while the graphics card was in a low-power state. This creates a denial of service situation and the GPU and connected display...

The vulnerability of the Intel i915 graphics driver of Intel microcomputer software allows a hacker to alter the entries in the memory page table by manipulating MMIO (Memory-Mapped Input Output) operations, thereby increasing their privileges.

The vulnerability of the Intel i915 graphics driver in Intel microprogrammed software processors is related to the lack of security checks in the copy-to-memory instructions for bit arrays. Exploiting this vulnerability allows an attacker to alter memory page tables by manipulating MMIO...
