  "description": "In the Linux kernel, the following vulnerability has been resolved:  ntfs3: fix out-of-bounds read in ntfs_dir_emit() and hdr_find_e()  The bounds check in ntfs_dir_emit() compares fname-\u003Ename_len (a character count) against e-\u003Esize (a byte count) without accounting for the 2-byte-per-character UTF-16LE encoding or the ATTR_FILE_NAME header size:    if (fname-\u003Ename_len \u002B sizeof(struct NTFS_DE) \u003E le16_to_cpu(e-\u003Esize))  This computes: name_len \u002B 16 \u003E e_size  The correct check must account for the ATTR_FILE_NAME header (66 bytes before the name) and the UTF-16LE character size (2 bytes each):    sizeof(NTFS_DE) \u002B offsetof(ATTR_FILE_NAME, name) \u002B   name_len * sizeof(short) \u003E e_size  Which computes: 16 \u002B 66 \u002B name_len * 2 \u003E e_size  The correct calculation already exists as fname_full_size() in ntfs.h and is used in cmp_fnames(), namei.c, and fslog.c, but was not used in the readdir path.  A crafted NTFS image with an index entry containing a small e-\u003Esize but large fname-\u003Ename_len bypasses the current check, causing ntfs_utf16_to_nls() to read past the entry boundary.  Additionally, add a key_size validation in hdr_find_e() to ensure the declared key_size does not exceed the available entry data, preventing comparison functions from reading past entry boundaries on the lookup path.",
