Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 2.6.33.14

Description The issue is caused by an integer underflow in the dccp parse options function, which can be triggered by a remote attacker sending a Datagram Congestion Control Protocol (DCCP) packet with an invalid feature options length. This results in a buffer over-read, leading to a denial of service.

Recommendations For Linux kernel versions prior to 2.6.33.14, update to version 2.6.33.14 or later to resolve the issue.
