        "text": "A vulnerability in the RADIUS feature of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.\r\n\r\nThis vulnerability is due to improper handling of certain RADIUS requests. An attacker could exploit this vulnerability by sending a crafted RADIUS request directly to an affected device. A successful exploit could allow the attacker to cause the ISE node to become unavailable. For single node deployments in that condition, endpoints that have not already authenticated would be unable to access the network until the node comes back up on its own.\r\n\r\nCisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.\r\n\r\n\r\n\r\nThis advisory is part of a group of advisories. For a complete list of the advisories and links to them, see Cisco Advance Notification for Publication of September 16, 2026, Security Advisories [\"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-notice-jfxK98ZP\"].

Caution: Do not disable Session Services for RADIUS deployments because it will turn off all RADIUS services.\r\n\r\nFor information about which Cisco software releases are vulnerable, see the Fixed Software [\"#fs\"] section of this advisory.\r\n\r\nDetermine PSN and Session Services Configuration\r\n\r\nTo determine whether a node in the Cisco ISE deployment is a PSN, use the following steps:\r\n\r\nLog in to the Cisco ISE web-based management interface.\r\nClick the menu icon.\r\nChoose Administration \u003e System \u003e Deployment \u003e Deployment.\r\nLook under the General Settings tab.\r\nLook at the Policy Service section.\r\nIf the slider is enabled, the node might be affected by this vulnerability. Continue to Step 6.\r\nIf the slider is not enabled, the node is not affected by this vulnerability.\r\n\r\nReview the Enable Session Services check box.\r\nIf the box is checked (Session Services enabled), the node is affected by this vulnerability.\r\nIf the box is not checked (Session Services disabled), the node is not affected by this vulnerability. Caution: Do not disable Session Services for RADIUS nodes. It can be disabled for TACACS+ only nodes.\r\n\r\n\r\nAll nodes in the deployment must be checked individually.",
