In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: clear MSIX permission entry on shutdown
Add disabling/clearing of MSIX permission entries on device shutdown to
mirror the enabling of the MSIX entries on probe. Current code left the
MSIX enabled and the pasid entries still programmed at device shutdown.
A flaw was found in the Linux Kernel. The current code leaves the MSIX enabled and the pasid entries still programmed at device shutdown. Add disabling/clearing of MSIX permission entries on device shutdown to mirror the enabling of the MSIX entries on probe.
