      "title": "fs/ntfs3: add bounds check to run_get_highest_vcn()",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nfs/ntfs3: add bounds check to run_get_highest_vcn()\n\nrun_get_highest_vcn() parses a packed NTFS mapping-pairs buffer without\nany length bound, relying solely on a 0x00 terminator to stop.  A\ncrafted $LogFile UpdateMappingPairs record whose embedded attribute\ncontains mapping-pairs runs without a terminator causes the function to\nread past the slab allocation, triggering a KASAN slab-out-of-bounds\nread on mount.\n\nThe sibling function run_unpack() received an analogous bounds-check in\ncommit b62567bca474 (\"ntfs3: add buffer boundary checks to run_unpack()\"),\nbut run_get_highest_vcn() was missed.\n\nTake a run_buf_size parameter and reject any run header whose payload\nwould extend past the buffer end, mirroring the pattern used by\nrun_unpack().  The caller in fslog.c passes the remaining attribute\nbytes after the mapping-pairs offset.\n\nKASAN report (on mainline v7.1 merge window HEAD):\n\n  BUG: KASAN: slab-out-of-bounds in run_get_highest_vcn+0x3c0/0x410\n  Read of size 1 at addr ffff88800e2d5400 by task mount/72\n  Call Trace:\n   run_get_highest_vcn+0x3c0/0x410\n   do_action.isra.0+0x3ba8/0x7b50\n   log_replay+0x9ddd/0x10200\n   ntfs_loadlog_and_replay+0x4ad/0x610\n   ntfs_fill_super+0x214a/0x4540",
