Description GLSAMaker/CVETool Bot gentoo-dev 2015-06-21 13:35:35 UTC 
CVE-2014-7822 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-7822):
  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.
