  "details" : [ "The XFS_IS_REALTIME_INODE macro in fs/xfs/xfs_linux.h in the Linux kernel before 4.13.2 does not verify that a filesystem has a realtime device, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via vectors related to setting an RHINHERIT flag on a directory.", "A flaw was found where the XFS filesystem code mishandles a user-settable inode flag in the Linux kernel prior to 4.14-rc1. This can cause a local denial of service via a kernel panic." ],
  "statement" : "This issue does not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 5, 6, 7  as the code with the flaw is not built in these products due to theirs build configuration.\nThis issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux MRG-2. Future updates for the respective releases may address this issue.",
