cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results).
cbq_classify en net/sched/sch_cbq.c en el kernel de Linux hasta 6.1.4 permite a los atacantes provocar una denegación de servicio (lectura fuera de los límites) debido a confusión de tipos (los números no negativos a veces pueden indicar una condición TC_ACT_SHOT en lugar de resultados de clasificación válidos).
