CVE-2011-2699

HighCVSS 7.5/10Last modified Jun 16, 2026

Description

The IPv6 implementation in the Linux kernel before 3.1 does not generate Fragment Identification values separately for each destination, which makes it easier for remote attackers to cause a denial of service (disrupted networking) by predicting these values and sending crafted packets.
