SUSE CVE-2026-86856

A flaw was found in the DPDK nfp vDPA driver. Stack and heap buffers sized for a single queue pair can be overflowed when more virtqueues are configured, leading to a host crash or memory corruption...

SUSE CVE-2026-93683

A flaw was found in the DPDK vhost library. When handling a virtio indirect descriptor table, the host reads the table length more than once from guest memory and can allocate a host copy before validating that length. A guest that changes the length between those reads, or that supplies an...

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

In the Linux kernel, the following vulnerabilities have been resolved: vhost/vdpa: The vhostvdpammap and vhostvdpafault functions use vma-vmpgoff as a virtqueue index for getvqnotification, but they do not validate that the index is smaller than v-nvqs. The ioctl path already performs both a boun...
