CVE-2026-64072
A flaw was found in the Linux kernel's Non-Volatile Memory Express NVMe subsystem. This vulnerability occurs when an integrity mapping fails, leading to a 'bio' block I/O leak. This resource leak can potentially lead to a denial of service DoS due to resource exhaustion...
CVE-2026-64071
In the Linux kernel, the following vulnerability has been resolved: nvme-pci: fix use-after-free in nvmefreehostmem nvmefreehostmem frees dev-hmbsgt via dmafreenoncontiguous but never clears the pointer afterward. This leads to a use-after-free if nvmefreehostmem is called twice in the same error...
CVE-2026-64019
In the Linux kernel, the following vulnerability has been resolved: nvme-pci: fix dma mapping leak on data setup error We're leaking the initial DMA mapping during iteration if we fail to allocate the tracking descriptor for both PRP and SGL. Unmap the iterator directly; we can't use the existing...
CVE-2026-64071
The CVE-2026-64071 issue is a use-after-free in the Linux kernel nvme-pci path. In nvme_free_host_mem(), dev->hmb_sgt is freed via dma_free_noncontiguous() but the pointer is not cleared, so a second call in the nvme_probe() error path (nvme_setup_host_mem() succeeds, nvme_set_host_mem() fails...
CVE-2026-64072
The CVE-2026-64072 vulnerability affects the Linux kernel, specifically the NVMe I/O path. It describes a fix for a bio leak that occurred when an integrity mapping failed during mapping; the code could leak a local bio because it was treated as NULL. The root cause is that the kernel attempted t...
CVE-2026-64072 nvme: fix bio leak on mapping failure
In the Linux kernel, the following vulnerability has been resolved: nvme: fix bio leak on mapping failure The local bio is always NULL, so we'd leak the bio if the integrity mapping failed. Just get it directly from the request...
EUVD-2026-45593
In the Linux kernel, the following vulnerability has been resolved: nvme-pci: fix dmavecs leak on p2p memory We don't unmap P2P memory, so we don't need to track it. The dmavec allocation was getting leaked on the completion...
CVE-2026-64020 nvme-pci: fix dma_vecs leak on p2p memory
In the Linux kernel, the following vulnerability has been resolved: nvme-pci: fix dmavecs leak on p2p memory We don't unmap P2P memory, so we don't need to track it. The dmavec allocation was getting leaked on the completion...
