GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

CVE-2014-7822 (GCVE-0-2014-7822)

Vulnerability from cvelistv5 – Published: 2015-03-16 10:00 – Updated: 2024-08-06 13:03
VLAI
Summary
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.
Severity
