The vulnerability affects multiple IOS XR versions including 7.5.x through 7.9.x. Exploitation does not require user interaction but does require local authentication and high privileges. No known exploits are currently reported in the wild. This vulnerability poses a significant risk to network infrastructure devices running affected IOS XR versions, especially in environments where local access is possible.
