"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nntfs: take invalidate_lock in ntfs_setattr_size()\n\nntfs_setattr_size() updates i_size and resizes the on-disk attribute\nwithout holding mapping->invalidate_lock. Page faults take the lock\nshared, so a fault racing the resize can resolve a VCN against the\ntransient runlist state of ntfs_non_resident_attr_expand() and fail\nwith a spurious SIGBUS, and can interleave with the size-change\nepilogue (truncate_pagecache(), i_size_write(),\npagecache_isize_extended()).\n\nTake invalidate_lock exclusively around the whole resize after\ninode_dio_wait(), matching the fallocate path and other filesystems\nsuch as xfs, which wraps truncate in its mmaplock (= invalidate_lock)."
