What it actually does

Out-of-bounds read in fq_pie_qdisc_enqueue when traffic classification selects an invalid flow index (q->flows + q->flows_cnt) beyond the allocated memory region for the fq_pie qdisc structure.

Why it matters to the business

Systems using the fq_pie qdisc for traffic shaping may experience kernel crashes, leading to denial of service; in rare cases memory disclosure could aid further attacks on network infrastructure hosts.

How an attack unfolds

An attacker with local or network-adjacent access configures an fq_pie qdisc with a low flow count, adds a clsact filter that forces a high priority value, then injects packets that cause the scheduler to index past the end of the flow array during enqueue, triggering the out-of-bounds read.

How to fix it

Upgrade the Linux kernel to a version containing the fix for the fq_pie flow selection logic; rebuild and reboot systems that use fq_pie qdiscs; consider temporarily replacing fq_pie with another scheduler such as fq_codel if immediate patching is not feasible.

How to confirm the fix worked

Confirm the kernel version contains the upstream commit that changes fq_pie flow index validation; reproduce the tc script and ping test and verify absence of KASAN splats; run kernel memory safety tools or syzkaller targeting sch_fq_pie.

Typical attack path

  1. Add fq_pie qdisc with small flows parameter via tc
  2. Attach clsact qdisc and egress matchall filter that sets high skb priority
  3. Send crafted packets (e.g., ICMP) that reach fq_pie_qdisc_enqueue
  4. Kernel performs invalid array access resulting in KASAN-detected slab OOB read

How to detect it

Search kernel logs and dmesg for KASAN reports containing fq_pie_qdisc_enqueue and slab-out-of-bounds; inspect auditd or system call traces for sequences of tc qdisc add commands followed by high-volume packet transmission on the same interface.

  • fq_pie_qdisc_enqueue+0x1314
  • BUG: KASAN: slab-out-of-bounds in fq_pie
  • tc qdisc add.*fq_pie flows 2
  • matchall action skbedit priority 0x10002

What your security team should do

  • Prioritize kernel updates on all hosts that expose network interfaces using fq_pie
  • Audit tc qdisc configurations for fq_pie usage and replace where possible
  • Monitor kernel logs for fq_pie-related OOB warnings
  • Test patched kernels in staging before broad deployment
