CVE-2006-2275

High
Published: Translated: NVD NIST

Summary

A vulnerability in the Linux SCTP (lksctp) implementation before version 2.6.17 allows a remote attacker to cause a denial of service (deadlock) by sending a large number of small messages to a receiver application that cannot process them quickly enough. This leads to spillover of the receive buffer and system lockup.

Risk Assessment

An attacker can remotely trigger a denial of service (DoS) by locking up the system or application using SCTP, potentially disrupting network services and affecting system availability.

Recommendation

Immediately update the Linux kernel to version 2.6.17 or later, which includes a fix that eliminates the deadlock vulnerability in the SCTP stack.
