  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nntfs3: add buffer boundary checks to run_unpack()\n\nrun_unpack() checks `run_buf \u003c 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.\n\nAdd boundary checks before each run_unpack_s64() call to ensure the\ndeclared field size does not exceed the remaining buffer.\n\nFound by fuzzing with a source-patched harness (LibAFL + QEMU).",
