Описание
The sanity_check_raw_super function in fs/f2fs/super.c in the Linux kernel before 4.11.1 does not validate the segment count, which allows local users to gain privileges via unspecified vectors.
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.
Отчет
This issue does not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 5, 6, 7 and Red Hat Enterprise MRG 2 as the code with the flaw is not built and shipped with the products listed.
