| Vetor | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions through 4.8.11
Description
The issue allows local users to bypass integer overflow checks, potentially causing a denial of service (memory corruption) or having unspecified other impact. This is achieved by leveraging access to a vfio PCI device file for a VFIO DEVICE SET IRQS ioctl call, which is described as a state machine confusion bug.
Recommendations
For Linux kernel versions through 4.8.11, update to a version later than 4.8.11 to resolve the issue. As a temporary workaround, consider restricting access to vfio PCI device files to minimize the risk of exploitation.
