Base vector

AV:N/AC:M/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 2.6.37-rc6

Description The issue allows remote attackers to cause a denial of service by sending a specific packet over UDP, resulting in a NULL pointer dereference and OOPS. This occurs when the Econet protocol is enabled and an Acorn Universal Networking (AUN) packet is sent.

Recommendations For Linux kernel versions prior to 2.6.37-rc6, update to version 2.6.37-rc6 or later to resolve the issue. As a temporary workaround, consider disabling the Econet protocol to minimize the risk of exploitation.
