  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nfs/ntfs3: terminate the cached volume label after UTF-8 conversion\n\nntfs_fill_super() loads the on-disk volume label with utf16s_to_utf8s()\nand stores the result in sbi-\u003evolume.label. The converted label is later\nexposed through ntfs3_label_show() using %s, but utf16s_to_utf8s() only\nreturns the number of bytes written and does not add a trailing NUL.\n\nIf the converted label fills the entire fixed buffer,\nntfs3_label_show() can read past the end of sbi-\u003evolume.label while\nlooking for a terminator.\n\nTerminate the cached label explicitly after a successful conversion and\nclamp the exact-full case to the last byte of the buffer.",
