  "cwe" : "CWE-1284",
  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nntfs3: add buffer boundary checks to run_unpack()\nrun_unpack() checks `run_buf < run_last` at the top of the while loop\nbut then reads size_size and offset_size bytes via run_unpack_s64()\nwithout verifying they fit within the remaining buffer.  A crafted NTFS\nimage with truncated run data in an MFT attribute triggers an OOB heap\nread of up to 15 bytes when the filesystem is mounted.\nAdd boundary checks before each run_unpack_s64() call to ensure the\ndeclared field size does not exceed the remaining buffer.\nFound by fuzzing with a source-patched harness (LibAFL + QEMU).", "A flaw was found in the Linux kernel's `ntfs3` module. A local attacker, by mounting a specially crafted NTFS (New Technology File System) image containing truncated run data, could trigger an out-of-bounds heap read. This vulnerability allows for the disclosure of sensitive information from kernel memory." ],
