Описание
The XFS subsystem in the Linux kernel through 4.8.2 allows local users to cause a denial of service (fdatasync failure and system hang) by using the vfs syscall group in the trinity program, related to a "page lock order bug in the XFS seek hole/data implementation."
The XFS subsystem in the Linux kernel 4.4 and later allows local users to cause a denial of service (fdatasync() failure and system hang) by using the vfs syscall group in the 'trinity' program, as a result of a page lock order bug in the XFS seek hole/data implementation.
Отчет
This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5, 6, 7 and MRG-2 as the code with the flaw is not present in the products listed.
