Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: vfio/cdx: Fixed NULL pointer dereferencing in the interrupt trigger path. Added validation to ensure that MSI is configured before accessing the cdxirqs array in vfiocdxsetmsitrigger. Without this check, userspace can cause a...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: vfio/cdx: Serialization of VFIODEVICESETIRQS with a per-device mutex The function vfiocdxsetmsitrigger reads vdev-configmsi and operates on the vdev-cdxirqs array based on its value. However, it does not provide any serialization...

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

CVE-2026-46034 affects the Linux kernel VFIO/PCI MSI handling: a NULL pointer dereference can occur in vfio_cdx_set_msi_trigger() if interrupts are triggered before MSIs are configured. The openSUSE Tumbleweed OpenSUSE-SU-2026:10954-1 advisory documents the fix in kernel-devel-7.0.11-1.1, noting ...
