Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 2.6.22.17

Description: The Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation contains a flaw that could result in memory corruptions. This issue arises because the IPv4-only inet sk rebuild header() function is used for both IPv4 and IPv6 DCCP connections. A remote attacker could exploit this flaw to crash the system.

Recommendations: For Linux kernel versions prior to 2.6.22.17, update to version 2.6.22.17 or later to resolve the issue. As a temporary workaround, consider restricting access to DCCP connections to minimize the risk of exploitation.
