  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nntfs: fail attrlist updates when the superblock is inactive\n\ngeneric_shutdown_super() clears SB_ACTIVE before evicting cached inodes.\nIf eviction selects the fake inode for a base inode's unnamed\n$ATTRIBUTE_LIST attribute, ntfs_evict_big_inode() drops the fake inode's\nreference on the base inode while the fake inode is still hashed and marked\nI_FREEING.\n\nThat iput can synchronously write back the base inode. The writeback path\nmay update mapping pairs and call ntfs_attrlist_update(), which\nunconditionally calls ntfs_attr_iget() for the same $ATTRIBUTE_LIST fake\ninode. VFS then finds the I_FREEING inode and waits for eviction to finish,\nbut the current task is still inside that eviction path, causing a\nself-deadlock in find_inode().\n\nFix this by mirroring the teardown guard used by __ntfs_write_inode():\nonce SB_ACTIVE has been cleared, do not try to iget the attribute-list\nfake inode. Return -EIO so teardown aborts the update instead of waiting on\nthe inode it is evicting.",
