| Doc Text: |
A flaw was found in the NILFS2 file system implementation in the Linux kernel. If nilfs_attach_log_writer() failed to create a log writer thread, it free'd a data structure of the log writer without any cleanup, causing a leak of struct nilfs_root. A user permitted to mount arbitrary file system images could use this flaw to cause a denial of service (resource exhaustion).
