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...
