In the Linux kernel, the following vulnerability has been resolved:

btrfs: fix missing last_unlink_trans update when removing a directory

When removing a directory we are not updating its last_unlink_trans field, which can result in incorrect fsync behaviour in case some one fsyncs the directory after it was removed because it's holding a file descriptor on it.

Example scenario:

mkdir /mnt/dir1 mkdir /mnt/dir1/dir2 mkdir /mnt/dir3

sync -f /mnt

# Do some change to the directory and fsync it. chmod 700 /mnt/dir1 xfs_io -c fsync /mnt/dir1

# Move dir2 out of dir1 so that dir1 becomes empty. mv /mnt/dir1/dir2 /mnt/dir3/

open fd on /mnt/dir1 call rmdir(2) on path "/mnt/dir1" fsync fd

When attempting to mount the filesystem, the log replay will fail with an -EIO error and dmesg/syslog has the following:
