CVE-2014-7822: Linux Kernel

High severity, CVSS 7.2. EPSS: 1.2% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: up to and including 3.15.8
