The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ocfs2: fix circular locking dependency in ocfs2_dio_end_io_write A circular locking dependency involves     INODE_ALLOC_SYSTEM_INODE, EXTENT_ALLOC_SYSTEM_INODE, and ORPHAN_DIR_SYSTEM_INODE. 1. ocfs2_mknod()     acquires INODE_ALLOC then EXTENT_ALLOC. 2. ocfs2_dio_end_io_write() acquires EXTENT_ALLOC for unwritten     extents, then ORPHAN_DIR via ocfs2_del_inode_from_orphan() while still holding EXTENT_ALLOC. 3.
    ocfs2_wipe_inode() acquires ORPHAN_DIR then INODE_ALLOC via ocfs2_remove_inode. Break the cycle in     ocfs2_dio_end_io_write() by freeing the allocation contexts (releasing EXTENT_ALLOC) before acquiring     ORPHAN_DIR. WARNING: possible circular locking dependency detected
