The saa7164_bus_get function in drivers/media/pci/saa7164/saa7164-bus.c in
the Linux kernel through 4.11.5 allows local users to cause a denial of
service (out-of-bounds array access) or possibly have unspecified other
impact by changing a certain sequence-number value, aka a “double fetch”
vulnerability.
