CVE-2026-23174

The CVE-2026-23174 entry concerns the Linux kernel nvme-pci subsystem. Root cause: dma_needs_unmap may switch from false to true during data-iterator mapping, and the nvme driver must preserve mapped DMA vectors for later unmapping. The fix is to allocate/unprepare storage for DMA vectors on dema...

CVE-2026-23174 nvme-pci: handle changing device dma map requirements

In the Linux kernel, the following vulnerability has been resolved: nvme-pci: handle changing device dma map requirements The initial state of dmaneedsunmap may be false, but change to true while mapping the data iterator. Enabling swiotlb is one such case that can change the result. The nvme...
