This ensures that all access via DMABUFs is revoked before the function&#39;s BARs become inaccessible.</p> <p>This fixes an issue where, if the function is disabled first, a tiny window exists in which the function&#39;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.</p> <p><strong>Affected:</strong> Linux, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>vfio/pci: Clean up DMABUFs before disabling function</p> <p>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().
