  "details": "In the Linux kernel, the following vulnerability has been resolved:  fs/ntfs3: prevent uninitialized lcn caused by zero len  syzbot reported a uninit-value in ntfs_iomap_begin [1].  Since runs was not touched yet, run_lookup_entry() immediately fails and returns false, which makes the value of \"*len\" 0. Simultaneously, the new value and err value are also 0, causing the logic in attr_data_get_block_locked() to jump directly to ok, ultimately resulting in *lcn being triggered before it is set [1].  In ntfs_iomap_begin(), the check for a 0 value in clen is moved forward to before updating lcn to avoid this [1].
