    CVE-2014-7822

    Published: 16 Mar 2015Last Modified: 10 Apr 2026

    Summary:

    Details: 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.
