Title
f2fs: fix to do sanity check on node blkaddr in truncate_node()
Summary
In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to do sanity check on node blkaddr in truncate_node() syzbot reports a f2fs bug as below: ------------[ cut here ]------------ kernel BUG at fs/f2fs/segment.c:2534!
