kernel: denial of service vector through vfio DMA mappings
Published Apr 24, 2019

MEDIUMCVSS 3.1
EPSS 0.54%
Description
A flaw was found in the Linux kernel's vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS). Versions 3.10, 4.14 and 4.18 are vulnerable.
