How to fix?

There is no fixed version for Centos:10 kernel-64k-devel-matched.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-devel-matched package and not the kernel-64k-devel-matched package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

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

vfio/pci: Clean up DMABUFs before disabling function

On device shutdown, make vfio_pci_core_close_device() call vfio_pci_dma_buf_cleanup() before the function is disabled via vfio_pci_core_disable(). This ensures that all access via DMABUFs is revoked before the function's BARs become inaccessible.

This fixes an issue where, if the function is disabled first, a tiny window exists in which the function's MSE is cleared and yet BARs could still be accessed via the DMABUF. The resources would also be freed and up for grabs by a different driver.
