CVE-2026-46141

A flaw was found in the Linux kernel's powerpc/xive interrupt controller. This vulnerability, identified as a kernel memory leak kmemleak, occurs when allocating Message Signaled Interrupts eXtended MSI-X vectors for NVMe devices. Due to an incorrect lookup of interrupt data, the xiveirqdata...

SUSE CVE-2026-46034

In the Linux kernel, the following vulnerability has been resolved: vfio/cdx: Fix NULL pointer dereference in interrupt trigger path Add validation to ensure MSI is configured before accessing cdxirqs array in vfiocdxsetmsitrigger. Without this check, userspace can trigger a NULL pointer...

CVE-2026-46034

A flaw was found in the Linux kernel's vfio/cdx module. A local user can cause a system crash by improperly configuring Message Signaled Interrupts MSI before they are set up. This can lead to a NULL pointer dereference, resulting in a Denial of Service DoS for the system...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the vfio/cdx driver’s failure to verify whether MSI is configured during the interrupt trigger...

CVE-2026-23361

A flaw was found in the Linux kernel. A race condition exists in the handling of Message Signaled Interrupts eXtended MSI-X within the PCI subsystem. When an MSI-X interrupt is raised, a PCI posted write transaction may not complete before its associated Address Translation Unit ATU entry is...

EUVD-2026-15340

In the Linux kernel, the following vulnerability has been resolved: PCI: dwc: ep: Flush MSI-X write before unmapping its ATU entry Endpoint drivers use dwpcieepraisemsixirq to raise an MSI-X interrupt to the host using a writel, which generates a PCI posted write transaction. There's no completio...
