Vulnerability from github – Published: 2025-08-22 18:31 – Updated: 2025-11-26 18:30

Details

In the Linux kernel, the following vulnerability has been resolved:

vfio/pds: Fix missing detach_ioas op

When CONFIG_IOMMUFD is enabled and a device is bound to the pds_vfio_pci driver, the following WARN_ON() trace is seen and probe fails:

WARNING: CPU: 0 PID: 5040 at drivers/vfio/vfio_main.c:317 __vfio_register_dev+0x130/0x140 [vfio] <...> pds_vfio_pci 0000:08:00.1: probe with driver pds_vfio_pci failed with error -22

This is because the driver's vfio_device_ops.detach_ioas isn't set.

Fix this by using the generic vfio_iommufd_physical_detach_ioas function.

Severity

5.5 (Medium)
