CVE-2026-46142 is a newly published Linux kernel vulnerability, received by NVD on May 28, 2026 from kernel.org, affecting the Wangxun libwx Ethernet driver when a virtual function reads a physical-function-only register during initialization and can hang the system. The fix is small, but the...

CVE-2026-46132 is a Linux kernel information-disclosure flaw published by NVD on May 28, 2026, after kernel.org reported that rtnetlink could leak up to 26 bytes of uninitialized kernel stack data per virtual function in certain SR-IOV network interface queries. The bug is not a Windows...

The QEMU SR-IOV implementation contains a subtle but meaningful bug: hw/pci/pcie_sriov.c in QEMU through 10.0.3 mishandles the VF Enable bit write mask, a logic error tracked as CVE-2025-54567 that can lead to incorrect registration/unregistration of virtual functions (VFs) and inconsistent...

A small but important kernel change — replacing a sleeping mutex with a non‑sleeping spinlock in the AMDGPU driver’s RLCG register access path — has been tracked as CVE‑2025‑38104 and fixed upstream to eliminate a priority‑inversion and invalid‑wait context that could trigger kernel oopses or...

A newly disclosed Linux kernel vulnerability, tracked as CVE-2025-40219, fixes a long-standing race and locking gap in the kernel’s PCI I/O virtualization (PCI/IOV) SR-IOV code: enabling and disabling SR-IOV did not take the global PCI “rescan‑remove” serialization lock, allowing concurrent...
