CVE-2026-23379 net/sched: ets: fix divide by zero in the offload path

In the Linux kernel, the following vulnerability has been resolved: net/sched: ets: fix divide by zero in the offload path Offloading ETS requires computing each class' WRR weight: this is done by averaging over the sums of quanta as 'qsum' and 'qpsum'. Using unsigned int, the same integer size a...

CVE-2026-23340

In the Linux kernel, the following vulnerability has been resolved: net: sched: avoid qdiscresetalltxgt vs dequeue race for lockless qdiscs When shrinking the number of real tx queues, netifsetrealnumtxqueues calls qdiscresetalltxgt to flush qdiscs for queues which will no longer be used...

CVE-2026-23340

CVE-2026-23340 affects the Linux kernel net sched subsystem where qdisc_reset_all_tx_gt() can race with the lockless dequeue path, potentially causing use-after-free of skbs when the number of real TX queues changes (e.g., via ethtool -L on virtio-net). The fix is to serialize qdisc_reset() again...

CVE-2026-23320

CVE-2026-23320 concerns the Linux kernel USB gadget f_ncm driver. The root cause is that the net_device was allocated in ncm_alloc_inst() and freed in ncm_free_inst(), tying the interface lifetime to the configuration instance rather than the USB connection, which can cause the network interface ...
