Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.11.7 EosKernel-3.4

Description The issue allows attackers to cause a denial of service, resulting in an infinite loop and crash. This can be triggered remotely through the network by sending certain malformed packets, specifically IP packets with rarely used packet options. The exposure is specific to certain EOS releases that use the affected EosKernel-3.4.

Recommendations For Linux kernel versions prior to 3.11.7, update to version 3.11.7 or later to resolve the issue. For EosKernel-3.4, follow the resolution steps documented in the relevant sections for the affected Arista EOS versions. As a temporary workaround, consider restricting network access to minimize the risk of exploitation.
