CVE-2006-2275: Canonical Ubuntu Linux

High severity, CVSS 7.5. EPSS: 3.6% chance of exploitation in the next 30 days.

Linux SCTP (lksctp) before 2.6.17 allows remote attackers to cause a denial of service (deadlock) via a large number of small messages to a receiver application that cannot process the messages quickly enough, which leads to "spillover of the receive buffer."

Affected products

• Canonical Ubuntu Linux: version 5.04 only; version 5.10 only; version 6.06 only
• Lksctp Stream Control Transmission Protocol: before 2.6.17 (fixed in 2.6.17)
