** Description changed: - tc_fill_qdisc() should not be called for builtin qdisc, or it - dereference a NULL pointer to get device ifindex. + The qdisc_notify function in net/sched/sch_api.c in the Linux kernel + before 2.6.35 does not prevent tc_fill_qdisc function calls referencing + builtin (aka CQ_F_BUILTIN) Qdisc structures, which allows local users to + cause a denial of service (NULL pointer dereference and OOPS) or + possibly have unspecified other impact via a crafted call. Break-Fix: - 53b0f08042f04813cd1a7473dacd3edfacb28eb3
