K17237 : Linux kernel vulnerability CVE-2014-7822

Security Advisory Description

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. (CVE-2014-7822)

Impact

An authenticated attacker may be able to cause a denial-of-service (DoS) attack, or other attack with an unspecified impact. This vulnerability is considered local, because it is exploitable only by an authenticated user that accesses the system by using the command line.
