In the Linux kernel, the following vulnerability has been resolved:
netfs, afs: Fix write skipping in dir/link writepages
Fix netfs write single() and afs single writepages() to better handle a
write that would be skipped due to lock contention and WB SYNC NONE by
returning 1 from netfs write single() if it skipped and making
afs single writepages() skip also. If a skip occurs, the inode must be
re-marked as the VFS may have cleared the mark.
This is really only theoretical for directories in netfs write single() as
the only path to that is through afs single writepages() that takes the
->validate lock around it, thereby serialising it.
