Linux Distros Unpatched Vulnerability : CVE-2026-46036

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - vfio/cdx: Serialize VFIODEVICESETIRQS with a per-device mutex vfiocdxsetmsitrigger reads vdev-configmsi and operates on the vdev-cdxirqs array based on its valu...

SUSE CVE-2026-46036

In the Linux kernel, the following vulnerability has been resolved: vfio/cdx: Serialize VFIODEVICESETIRQS with a per-device mutex vfiocdxsetmsitrigger reads vdev-configmsi and operates on the vdev-cdxirqs array based on its value, but provides no serialization against concurrent VFIODEVICESETIRQS...

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...

CVE-2026-46036

The CVE covers a race in the Linux kernel vfio/cdx driver where concurrent VFIO_DEVICE_SET_IRQS ioctls can observe inconsistent state of config_msi and cdx_irqs, leading to use-after-free of the cdx_irqs array. A per-device mutex (cdx_irqs_lock) is added to struct vfio_cdx_device and is acquired ...

CVE-2026-46034

The CVE-2026-46034 issue affects the Linux kernel VFIO/cdx path, where NULL pointer dereference could occur in the interrupt trigger path if userspace calls VFIO_DEVICE_SET_IRQS with DATA_BOOL/DATA_NONE before interrupts are set up via VFIO_IRQ_SET_DATA_EVENTFD. The root cause is missing enforcem...
