CVE-2026-23174

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> nvme-pci: handle changing device dma map requirements<br /> <br /> The initial state of dma_needs_unmap may be false, but change to true<br /> while mapping the data iterator. Enabling swiotlb is one such case that<br /> can change the result. The nvme driver needs to save the mapped dma<br /> vectors to be unmapped later, so allocate as needed during iteration<br /> rather than assume it was always allocated at the beginning. This fixes<br /> a NULL dereference from accessing an uninitialized dma_vecs when the<br /> device dma unmapping requirements change mid-iteration.
