CVE-2014-7822 EXPLOIT
7.2
HIGH · CVSS 2.0 · EPSS 1.2% (pctl 67)
Patch early
A public exploit exists.
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.
