Summary
In the Linux kernel, the following vulnerability has been resolved: fuse: write inode in fuse_release() A race between write(2) and close(2) allows pages to be dirtied after fuse_flush -> write_inode_now(). If these pages are not flushed from fuse_release(), then there might not be a writable open file later. So any remaining dirty pages must be written back before the file is released. This is a partial revert of the blamed commit.
