Unrestricted File Size Vulnerability in Linux Kernel Splice Write Operations

CVE-2014-7822 · HIGH Severity

AV:L/AC:L/AU:N/C:C/I:C/A:C

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.
