drivers/vfio/pci/vfio_pci_intrs.c in the Linux kernel through 4.8.11 misuses the kzalloc function, which allows local users to cause a denial of service (integer overflow) or have unspecified other impact by leveraging access to a vfio PCI device file.

Security readout for executives and security teams

This is an old Linux kernel VFIO PCI flaw. A local user with access to a VFIO PCI device file could trigger an integer-overflow-related allocation bug, causing denial of service or other unspecified impact. It matters mainly where VFIO is used for device passthrough, virtualization, or hardware-assigned workloads. Exposure is likely limited to Linux systems running affected kernels with VFIO PCI enabled and local users or workloads allowed access to VFIO PCI device files. Treat as a targeted maintenance item, not an emergency. Prioritize virtualization or hardware passthrough hosts where untrusted local users or tenants can access VFIO devices. Mitigation focus: Update to a vendor-supported kernel containing the upstream fix or vendor backport.; Review Red Hat advisories if operating affected Red Hat kernel packages.; Restrict VFIO PCI device file access to trusted administrators and workloads..
