  "details": "In the Linux kernel, the following vulnerability has been resolved:  ntfs: fix off-by-one in mapping pairs decoding bounds checks  In ntfs_mapping_pairs_decompress(), attr_end points one byte past the end of the attribute record:      attr_end = (u8 *)attr + le32_to_cpu(attr-\u003elength);  The two bounds checks validating that mapping pair data bytes fit within the attribute use strict greater-than (\u003e), which allows a one-byte out-of-bounds read when the data extends exactly to attr_end:    b = *buf \u0026 0xf;   if (b) {       if (unlikely(buf + b \u003e attr_end))   // off-by-one           goto io_error;       for (deltaxcn = (s8)buf[b--]; b; b--)           deltaxcn = (deltaxcn \u003c\u003c 8) + buf[b];   }  When buf + b == attr_end, the check evaluates to false and buf[b] reads one byte past the valid attribute boundary. The same pattern appears in the LCN delta bytes check.  Fix both checks to use \u003e= so that buf[b] at exactly attr_end is correctly rejected as out of bounds.",
