  "description": "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.",
