{
    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nntfs3: fix integer overflow in run_unpack() volume boundary check\n\nThe volume boundary check `lcn + len > sbi->used.bitmap.nbits` uses raw\naddition which can wrap around for large lcn and len values, bypassing\nthe validation.  Use check_add_overflow() as is already done for the\nadjacent prev_lcn + dlcn and vcn64 + len checks added by commit\n3ac37e100385 (\"ntfs3: Fix integer overflow in run_unpack()\").\n\nFound by fuzzing with a source-patched harness (LibAFL + QEMU).",
