CVE-2011-2525

Priority
Description
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.
Ubuntu-Description
Ben Pfaff discovered that Classless Queuing Disciplines (qdiscs) were being
incorrectly handled. A local attacker could exploit this to crash the
system, leading to a denial of service.
