For example, qfq_dump_class may trigger a NULL dereference, and qfq_delete_class may cause a use-after-free.</p> <p>This patch addresses the issue by:</p> <p>1. Moved qfq_destroy_class into the critical section.</p> <p>2. Added sch_tree_lock protection to qfq_dump_class and qfq_dump_class_stats.</p> <p><strong>Affected:</strong> Linux, Siemens SIMATIC S7-1500 CPU 1518-4 PN/DP MFP, Siemens SIMATIC S7-1500 CPU 1518F-4 PN/DP MFP, Siemens SIPLUS S7-1500 CPU 1518-4 PN/DP MFP</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>net/sched: sch_qfq: Fix race condition on qfq_aggregate</p> <p>A race condition can occur when &#39;agg&#39; is modified in qfq_change_agg (called during qfq_enqueue) while other threads access it concurrently.
