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).","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/9cc5761b8f28f9cef72061094eb5e37e2cd44d97","tags":[]},{"url":"https://git.kernel.org/stable/c/f0b0738ba95731eeafd11352c74f8b48951f67dc","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
