CVE-2025-39677
CVE-2025-39677: In the Linux kernel, backlog accounting was fixed for qdisc_dequeue_internal affecting tbf-backed qdiscs (hhf, fq, fq_codel, fq_pie). The root cause was that when dropping packets to satisfy a new limit, only qlen was accounted for for some cases (gso_skb path), omitting qdisc_qst...
kernel: net_sched: hfsc: Fix a potential UAF in hfsc_dequeue() too
In the Linux kernel, the following vulnerability has been resolved: netsched: hfsc: Fix a potential UAF in hfscdequeue too Similarly to the previous patch, we need to safe guard hfscdequeue too. But for this one, we don't have a reliable reproducer...
kernel: sch_hfsc: Fix qlen accounting bug when using peek in hfsc_enqueue()
A flaw was found in the HFSC queueing discipline implementation in the Linux kernel. When a packet is enqueued and the child qdisc's peek function is called before properly updating the HFSC queue's length and backlog counters, a race condition can occur. In some cases, the peek operation may...

CVE-2025-38553
CVE-2025-38553 affects the Linux kernel (net/sched). The issue concerns the duplication logic for netem instances in a qdisc tree, where the existing netem_enqueue handling can misbehave when a netem coexists with others, potentially causing a soft lockup or OOM loop in netem_dequeue. The connect...
