The kernel memory of affected devices is exposed to user-mode via direct memory access (DMA) which could allow a local attacker with administrative privileges to execute arbitrary code on the host system without any restrictions. Affected devices insufficiently control continuous mapping of direct memory access (DMA) requests. This could allow local attackers with administrative privileges to cause a denial of service situation on the host. A physical power cycle is required to get the system working again.
