Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: nvme-pci: fixed the issue of freeing the HMB descriptor table. The HMB descriptor table is sized based on the maximum number of descriptors that can be used for a given device. However, nvmeallochostmem might break out of the loo...

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-2026-64071

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...

Siemens SCALANCE and RUGGEDCOM Devices Improper Input Validation (CVE-2024-56756)

nvme-pci: vulnerability involves an incorrect size being passed to dmafreecoherent in nvme-pci due to nvmeallochostmem potentially using fewer descriptors than planned, which is fixed by ensuring the correct size is used for freeing the HMB descriptor table. This plugin only works with Tenable.ot...
