NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-debug-devel package and not the kernel-uek-debug-devel package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

The implementation of certain splice_write file operations in the Linux kernel before 3.16 does not enforce a restriction on the maximum size of a single file, which allows local users to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted splice system call, as demonstrated by use of a file descriptor associated with an ext4 filesystem.
