  descriptionMultiple integer overflows in the (1) agp_allocate_memory and (2) agp_create_user_memory functions in drivers/char/agp/generic.c in the Linux kernel before 2.6.38.5 allow local users to trigger buffer overflows, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via vectors related to calls that specify a large number of memory pages.

  nameCVE-2011-1751
  descriptionThe pciej_write function in hw/acpi_piix4.c in the PIIX4 Power Management emulation in qemu-kvm does not check if a device is hotpluggable before unplugging the PCI-ISA bridge, which allows privileged guest users to cause a denial of service (guest crash) and possibly execute arbitrary code by sending a crafted value to the 0xae08 (PCI_EJ_BASE) I/O port, which leads to a use-after-free related to "active qemu timers."
