CVE-2026-64019

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> nvme-pci: fix dma mapping leak on data setup error<br /> <br /> We&amp;#39;re leaking the initial DMA mapping during iteration if we fail to<br /> allocate the tracking descriptor for both PRP and SGL. Unmap the<br /> iterator directly; we can&amp;#39;t use the existing unmap helper because it<br /> depends on the tracking descriptor being successfully allocated, so a<br /> new one for an in-use iterator is provided.<br /> <br /> The mappings were also leaking when the driver detects an invalid<br /> bio_vec when mapping PRPs, so fix that too.
