      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nfs/ntfs3: bound attr_off in UpdateResidentValue against data_off\n\nIn do_action()'s UpdateResidentValue case (fslog.c:3307),\nlrh->attr_off and lrh->redo_len come from the on-disk LRH.\nWhen they satisfy aoff + dlen < attr->res.data_off, the\nassignment\n\n\tattr->res.data_size = cpu_to_le32(aoff + dlen - data_off);\n\nunderflows to ~4 GiB (e.g. 0xFFFFFFF9 when aoff=0x10, dlen=1,\ndata_off=0x18).  Subsequent code that reads attr->res.data_size\nto walk the resident attribute payload would then read up to\n4 GiB past the 1024-byte MFT record allocation.\n\nThe existing mi_enum_attr() defense in fs/ntfs3/record.c:287\ncatches the corrupted data_size on the next attribute walk\nand fails the mount, but only on the path that walks all\nattributes.  A read site that picks an attribute by name and\nreads its data_size without re-validating is not covered.\nValidate aoff against data_off and asize at the source.\n\nReproduced under UML+KASAN on mainline 8d90b09e6741 via\npr_warn-only probe: with aoff=0x10 and data_off=0x18, the\npost-assignment data_size is 0xfffffff9 (mount then fails\nat -22 from mi_enum_attr).\n\n[almaz.alexandrovich@paragon-software.com: clang-formatted the changes]",
