PT-2026-61648

In the Linux kernel, the following vulnerability has been resolved: net/sched: dualpi2: fix GSO backlog accounting When DualPI2 splits a GSO skb into N segments, it propagates N additional packets to its parent before returning NET XMIT SUCCESS. The parent then accounts for the original skb once...

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...

CVE-2025-38637

In the Linux kernel, the following vulnerability has been resolved: netsched: skbprio: Remove overly strict queue assertions In the current implementation, skbprio enqueue/dequeue contains an assertion that fails under certain conditions when SKBPRIO is used as a child qdisc under TBF with specif...

CVE-2025-38637

The CVE CVE-2025-38637 affects the Linux kernel skbprio queue in net_sched when used as a child qdisc under Token Bucket Filter (TBF). The root cause is an overly strict assertion in skbprio enqueue/dequeue that can miscount lengths because TBF may peek at packets without dequeueing when tokens a...

SUSE CVE-2024-56770

In the Linux kernel, the following vulnerability has been resolved: net/sched: netem: account for backlog updates from child qdisc In general, 'qlen' of any classful qdisc should keep track of the number of packets that the qdisc itself and all of its children holds. In case of netem, 'qlen' only...

CVE-2024-50039

In the Linux kernel, the following vulnerability has been resolved: net/sched: accept TCASTAB only for root qdisc Most qdiscs maintain their backlog using qdiscpktlenskb on the assumption it is invariant between the enqueue and dequeue handlers. Unfortunately syzbot can crash a host rather easily...

CVE-2021-47418

CVE-2021-47418 refers to a Linux kernel vulnerability in net_sched: a NULL pointer dereference inside fifo_set_limit() that could OOPS when adjusting limits on certain qdiscs (notably pfifo_fast, which lacks a change() operation). The issue was reproduced via syzbot and the fix makes fifo_set_lim...

CVE-2013-4563

The udp6ufofragment function in net/ipv6/udpoffload.c in the Linux kernel through 3.12, when UDP Fragmentation Offload UFO is enabled, does not properly perform a certain size comparison before inserting a fragment header, which allows remote attackers to cause a denial of service panic via a lar...
