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

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-2026-43449

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...
