    Subject[073/105] Bluetooth: sco: fix information leak to userspace
    2.6.38-stable review patch.  If anyone has any objections, please let us know.

    ------------------

    From: Vasiliy Kulikov <segoon@openwall.com>

    commit c4c896e1471aec3b004a693c689f60be3b17ac86 upstream.

    struct sco_conninfo has one padding byte in the end. Local variable
    cinfo of type sco_conninfo is copied to userspace with this uninizialized
    one byte, leading to old stack contents leak.
