CVE-2026-68330

CVE-2026-68330 relates to the Linux kernel net/airoha NPU mailbox handling. The issue arises because airoha_npu_send_msg() always maps the mailbox buffer with DMA_TO_DEVICE, while some callers expect the NPU to write the response back into the same buffer. On non‑cache‑coherent architectures (e.g...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic-its: Remove the reference to the translation cache only for the erased entry. The vgicitsinvalidatecache function iterates through the per-ITS translation cache using xaforeach, and removes the cache reference fo...

CVE-2026-64289

A flaw was found in the Linux kernel. In the iommufd component, the iommufdhwptinvalidate function allows a local user to provide excessively large values for entrynum and entrylen during cache invalidation. This can lead to a Denial of Service DoS by causing the system to become unresponsive...
