Visit Cisco security advisoriesMultiple vulnerabilities in the web-based management interface of Cisco IoT Field Network Director Software could allow an authenticated, remote attacker to access files, execute commands, and cause denial of service (DoS) conditions on managed routers. For more information about these vulnerabilities, see the Details section of this advisory.
Multiple vulnerabilities in Cisco IOS XR Software could allow an authenticated, local attacker to execute commands as root on an underlying operating system or gain full administrative control of an affected device. For more information about these vulnerabilities, see the Details section of this advisory. Cisco has released software updates that address these vulnerabilities. A workaround is available for one of the vulnerabilities. This advisory is part of the March 2026 release of the Cisco IOS XR Software Security Advisory Bundled Publication.

A vulnerability in the Intermediate System-to-Intermediate System (IS-IS) multi-instance routing feature of Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to cause the IS-IS process to restart unexpectedly. This vulnerability is due to insufficient input validation of ingress IS-IS packets. An attacker could exploit this vulnerability by sending crafted IS-IS packets to an affected device after forming an adjacency. A successful exploit could allow the attacker to cause the IS-IS process to restart unexpectedly, resulting in a temporary loss of connectivity to adver…
A vulnerability in the handling of an Egress Packet Network Interface (EPNI) Aligner interrupt in Cisco IOS XR Software for Cisco Network Convergence System (NCS) 5500 Series with NC57 line cards and Cisco NCS 5700 Routers and Cisco IOS XR Software for Third Party Software could allow an unauthenticated, remote attacker to cause the network processing unit (NPU) and ASIC to stop processing, preventing traffic from traversing the interface. This vulnerability is due to the corruption of packets in specific cases when an EPNI Aligner interrupt is triggered while an affected device is experien…
