CVE-2024-50135

Service interruption via NVMe queue-count race

Published Nov 5, 2024 · Updated May 11, 2026

Race condition in the Linux kernel NVMe PCI driver allows local users to interrupt service during concurrent reset and shutdown. nvme_pci_update_nr_queues() reads dev->online_queues without shutdown_lock while nvme_dev_disable() can change it, passing an invalid queue count to blk_mq_update_nr_hw_queues(). Triggering the fault requires local low-privileged access and a high-complexity reset-disable race; the observed path produces a kernel warning and availability loss.
