Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: fix race condition between reset and nvme_dev_disable()
nvme_dev_disable() modifies the dev->online_queues field, therefore nvme_pci_update_nr_queues() should avoid racing against it, otherwise we could end up passing invalid values to blk_mq_update_nr_hw_queues().
WARNING: CPU: 39 PID: 61303 at drivers/pci/msi/api.c:347
pci_irq_get_affinity+0x187/0x210
Workqueue: nvme-reset-wq nvme_reset_work [nvme]
RIP: 0010:pci_irq_get_affinity+0x187/0x210
Call Trace:
Fix the bug by locking the shutdown_lock mutex before using dev->online_queues. Give up if nvme_dev_disable() is running or if it has been executed already.
