kernel: splice: lack of generic write checks
Published Mar 16, 2015
7.2
HIGHCVSS 2.0
EPSS 1.18%
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.
