CVE-2026-43161

CVE-2026-43161 is a Linux kernel IOMMU VT-d vulnerability related to ATS invalidation when a PCIe endpoint loses connection. In scalable-mode-disabled/unsupported systems, an endpoint link drop can cause the IOMMU to wait indefinitely for an ATS invalidation, leading to a host hard-lock (notably ...

CVE-2026-43130

The CVE-2026-43130 issue affects the Linux kernel iommu/vt-d path, where flushing the dev-IOTLB can occur during resource release in scalable PCIe mode. The root cause is a path that attempted ATS invalidation without adequately verifying whether the PCIe device is still accessible after a link-d...

kernel: nvme: avoid double free special payload

A flaw was found in the Linux kernel's NVMe component. This vulnerability is due to a double free error that occurs when a discard request needs to be retried and fails before a new special payload is added. A local attacker could exploit this memory corruption issue to cause a denial of service...
