Description

drivers/vfio/pci/vfio_pci.c in the Linux kernel through 4.8.11 allows local users to bypass integer overflow checks, and cause a denial of service (memory corruption) or have unspecified other impact, by leveraging access to a vfio PCI device file for a VFIO_DEVICE_SET_IRQS ioctl call, aka a "state machine confusion bug."

Affected configurations

• linux linux kernel (>= 3.6 < 3.10.107) • linux linux kernel (>= 3.11 < 3.12.70) • linux linux kernel (>= 3.13 < 3.16.39) • linux linux kernel (>= 3.17 < 3.18.51) • linux linux kernel (>= 3.19 < 4.1.41) • linux linux kernel (>= 4.2 < 4.4.65) • linux linux kernel (>= 4.5 < 4.9)
