  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nntfs: avoid self-deadlock during inode eviction\n\nAn attribute-list update performed while allocating clusters can drop the\nlast reference to the temporary attribute inode. Evicting that inode\ndrops its reference to the base inode and can invoke ntfs_drop_big_inode()\nfor the base inode from within the base inode's own writeback path.\n\nIf the base inode is unlinked, ntfs_drop_big_inode() calls\ntruncate_setsize(), which waits for the inode's folio writeback to\ncomplete. The same writeback worker is responsible for completing that\nwriteback, so it waits for itself indefinitely.\n\nPrevent this self-deadlock by grabbing a reference to the base inode at the\nbeginning of ntfs_writepages() and releasing it at the end of the function.\nThis defers eviction until all bios have been submitted, allowing the wait\nfor folio writeback to complete safely.",
