Bugzilla:
1481146: CVE-2017-10662 kernel: Missing sanity check for segment count in f2fs
It was found that the sanity_check_raw_super() function in 'fs/f2fs/super.c' file in the Linux kernel before version 4.12-rc1 does not validate the f2fs filesystem segment count. This allows an unprivileged local user to cause a system panic and DoS. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.
