CVE-2026-43448

A flaw was found in the Linux kernel's nvme-pci driver. A race condition exists in the nvmepollirqdisable function, where the device can be concurrently disabled by nvmeresetwork. This can lead to an unbalanced interrupt IRQ enable operation, resulting in a kernel warning. This issue may cause...

CVE-2026-43449

CVE-2026-43449 concerns the Linux kernel NVMe PCI driver. The issue is a slab-out-of-bounds write in nvme_dbbuf_set caused by an incorrect loop bound when indexing dev->online_queues; index 0 (admin queue) is excluded, but the loop could overrun. The vulnerability is evidenced by KASAN reports...

CVE-2026-43449

In the Linux kernel, the following vulnerability has been resolved: nvme-pci: Fix slab-out-of-bounds in nvmedbbufset dev-onlinequeues is a count incremented in nvmeinitqueue. Thus, valid indices are 0 through dev-onlinequeues − 1. This patch fixes the loop condition to ensure the index stays with...

CVE-2026-43448 nvme-pci: Fix race bug in nvme_poll_irqdisable()

In the Linux kernel, the following vulnerability has been resolved: nvme-pci: Fix race bug in nvmepollirqdisable In the following scenario, pdev can be disabled between 1 and 3 by 2. This sets pdev-msixenabled = 0. Then, pciirqvector will return MSI-X IRQ15 for 1 whereas return INTx IRQcqvector...

CVE-2026-43448

CVE-2026-43448 corresponds to a race in the Linux kernel nvme-pci driver (nvme_poll_irqdisable) where a device can be disabled between operations, causing nvme_poll_irqdisable() to race with nvme_reset_work() and leading to an unbalanced IRQ enable (IRQ 10 in the crash log). The root cause is a m...
