CVE-2026-64476

A flaw was found in the Linux kernel's vfio/pci driver. The disableidled3 flag, which controls device power states, was handled as a global module parameter instead of being latched per device. This improper handling could lead to unbalanced Power Management PM operations for devices already boun...

CVE-2026-64475

A flaw was found in the Linux kernel's vfio/pci subsystem. A missing cleanup operation during device registration could lead to a stale registration and a callback using freed memory. This vulnerability could result in system instability or potentially lead to a denial of service...

CVE-2026-64472

A flaw was found in the Linux kernel's vfio/mlx5 subsystem. This vulnerability arises from non-atomic bitfield operations, where multiple updates to shared data structures can occur concurrently. This race condition may lead to unexpected behavior or data corruption due to inconsistent state,...

CVE-2026-64474

A flaw was found in the Linux kernel's Virtual Function I/O VFIO device migration feature. The vfiomiggetnextstate function, responsible for managing device migration states, contains an infinite loop. This occurs when processing certain blocked transitions, causing the system to hold a driver...

SUSE CVE-2026-64473

In the Linux kernel, the following vulnerability has been resolved: vfio: Remove device debugfs before releasing devres VFIO device debugfs files created with debugfscreatedevmseqfile store a devres allocated debugfsdevmentry as inode private data. vfiounregistergroupdev currently calls...

SUSE CVE-2026-64474

In the Linux kernel, the following vulnerability has been resolved: vfio: prevent infinite loop in vfiomiggetnextstate on blocked arc vfiomiggetnextstate walks vfiofromfsmtable one step at a time, looping to skip optional states the device does not support until nextfsm is supported. A blocked...

SUSE CVE-2026-64476

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Latch disableidled3 per device When disableidled3 was introduced in vfio-pci, it directly manipulated the device power state with pcisetpowerstate. There were no refcounts to maintain or balanced operations, we could...

CVE-2026-64475

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Release the VGA arbiter client on registerdevice failure The re-order in the Fixes commit below displaced vfiopcivgainit as the last failure point of what is now vfiopcicoreregisterdevice without introducing an unwind f...

CVE-2026-64472

In the Linux kernel, the following vulnerability has been resolved: vfio/mlx5: Fix racy bitfields and tighten struct layout Bitfield operations are not atomic, they use a read-modify-write pattern, therefore we should be careful not to pack bitfields that can be concurrently updated into the same...

CVE-2026-64476 vfio/pci: Latch disable_idle_d3 per device

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Latch disableidled3 per device When disableidled3 was introduced in vfio-pci, it directly manipulated the device power state with pcisetpowerstate. There were no refcounts to maintain or balanced operations, we could...

CVE-2026-64476

The CVE-2026-64476 vulnerability affects the Linux kernel vfio-pci driver. The root cause was improper handling of the disable_idle_d3 flag, which initially could be changed globally and influenced per-device power states via runtime_power management (PM). The issue arose because the vfio-pci mod...

CVE-2026-64475 vfio/pci: Release the VGA arbiter client on register_device() failure

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Release the VGA arbiter client on registerdevice failure The re-order in the Fixes commit below displaced vfiopcivgainit as the last failure point of what is now vfiopcicoreregisterdevice without introducing an unwind f...

CVE-2026-64475

CVE-2026-64475 concerns the Linux kernel VFIO PCI subsystem. The issue arises from a re-order in a Fixes sequence where vfio_pci_vga_init() was displaced as the last failure point inside vfio_pci_core_register_device(), without an unwind for the VGA arbiter registration. In current kernels this i...

CVE-2026-64474

The CVE-2026-64474 issue affects the Linux kernel VFIO path, specifically vfio_mig_get_next_state() which walks vfio_from_fsm_table[] and could spin forever when encountering an ERROR sentinel (STOP_COPY arcs to ERROR). The root cause was an unaccounted ERROR sentinel in the skip loop, allowing a...
