However, for successful exploitation to occur, the device must be configured as a tunnel endpoint with a decapsulation IP, such as a VXLAN VTEP, a GRE tunnel endpoint, or with an IP decap-group.\\n\\nThe network equipment company acknowledged that the vulnerability has been \\”reported as being exploited in the wild,\\” crediting Comcast’s Scott Christiansen, Lukas Peitz, Rich Compton, and Jonathan Davis for responsibly disclosing it.\\n\\nDespite this, Arista said no patches are being planned to address CVE-2026-7473, citing risks that doing so could break existing configurations on deployments. The company has outlined mitigations to address the issue.\\n\\n\\”There are two broad approaches to mitigate this issue – (1) applying ACLs on upstream devices or (2) applying ACLs on the devices where the unexpected decapsulation is happening,\\” Arista said. \\”In both cases, the idea is to either selectively allow only legitimate tunnel traffic or to selectively block malicious tunnel traffic.\\”\\n\\nFederal Civilian Executive Branch (FCEB) agencies have been ordered to apply the necessary fixes or mitigations by June 23, 2026, to counter the threat posed by the three vulnerabilities.\\n\\nFound this article interesting?
