CVE-2026-64020 Details
Description
In the Linux kernel, the following vulnerability has been resolved: nvme-pci: fix dma_vecs leak on p2p memory We don't unmap P2P memory, so we don't need to track it. The dma_vec allocation was getting leaked on the completion.
A vulnerability in the Linux kernel's NVMe PCI driver has been addressed, which involved a memory leak of DMA vector allocations related to peer-to-peer (P2P) memory. The issue arose because P2P memory was not being unmapped, leading to unnecessary tracking and leakage of DMA vectors upon completion. This vulnerability affects the stable version of the Linux kernel.
