The vulnerability of the `nvme_dbbuf_set()` function in the driver/nvme/host/pci.c module of the Linux NVME driver allows a attacker to escalate their privileges or execute arbitrary code.

The vulnerability of the nvmedbbufset function in the drivers/nvme/host/pci.c file of the NVME kernel driver in Linux is related to the execution of operations outside the buffer boundaries. Exploiting this vulnerability can allow an attacker to increase their privileges or execute arbitrary code...

CVE-2026-64071

A flaw was found in the Linux kernel's NVMe over PCI Express NVMe-PCIe driver. This vulnerability, a use-after-free error, occurs when the system attempts to free host memory twice in certain error handling scenarios, particularly during Host Memory Buffer HMB setup for NVMe devices. An attacker...

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...

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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 trac...

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

CVE-2026-64071 is a use-after-free in the Linux kernel's nvme-pci driver. The function nvme_free_host_mem() frees dev->hmb_sgt via dma_free_noncontiguous() but fails to NULL the pointer. When nvme_probe() triggers an I/O error during HMB setup, the error path calls nvme_free_host_mem() a secon...

CVE-2026-64072

CVE-2026-64072 is a bio leak in the Linux kernel NVMe driver . When integrity mapping fails, the code attempted to free a local bio pointer that was always NULL, leaking the actual bio that should have been obtained directly from the request. This results in a high availability impact (resource e...

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...
