# CVE-2014-7822

> 3.1 LOW · 🧪 PoC

## Beschreibung

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.

## Exploit-Evidenz

- [EDB-36743 — Linux Kernel 3.13/3.14 (Ubuntu) - 'splice()' System Call Local Denial of Service](https://www.exploit-db.com/exploits/36743)
