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 ...
