FKIE_CVE-2011-2525
Vulnerability from fkie_nvd - Published: 2012-02-02 04:09 - Updated: 2026-06-16 23:31
Severity
Summary
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.
