Description

In the Linux kernel, the following vulnerability has been resolved: net/sched: netem: fix queue limit check to include reordered packets The queue limit check in netem_enqueue() uses q->t_len which only counts packets in the internal tfifo. Packets placed in sch->q by the reorder path (__qdisc_enqueue_head) are not counted, allowing the total queue occupancy to exceed sch->limit under reordering. Include sch->q.qlen in the limit check.

Affected configurations

• linux linux kernel (>= 5.4.288 < 5.5) • linux linux kernel (>= 5.10.232 < 5.10.258) • linux linux kernel (>= 5.15.175 < 5.15.209) • linux linux kernel (>= 6.1.121 < 6.1.175) • linux linux kernel (>= 6.6.67 < 6.6.141) • linux linux kernel (>= 6.12.6 < 6.12.91) • linux linux kernel (>= 6.13.1 < 6.18.33) • linux linux kernel (>= 6.19 < 7.0.10) • linux linux kernel 6.13 • linux linux kernel 7.1
