CVE-2014-7822
Published: 16 March 2015
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.
From the Ubuntu Security Team
The Linux kernel's splice system call did not correctly validate its parameters. A local, unprivileged user could exploit this flaw to cause a denial of service (system crash).
