What the advisory describes

In the Linux kernel, the following vulnerability has been resolved: iommufd: Release current IOAS on xa_store() failure iommufd_take_all_iova_rwsem() takes an object reference and the iova_rwsem write lock before storing the IOAS in the temporary ioas_list xarray. If xa_store() fails, the current IOAS has not been inserted into ioas_list yet. iommufd_release_all_iova_rwsem() only unwinds IOAS objects already present in that xarray, so it cannot release the current IOAS. Release the current IOAS rwsem and object reference before unwinding the previously stored entries.

Source: EUVD (ENISA), in the words of the advisory.

Patchlage reports hits and suspected hits. About everything else this system says nothing — neither this page nor the situation report ever claims that an estate is safe.
