2024-09-11 CVE-2024-20317 Unspecified vulnerability in Cisco IOS XR
A vulnerability in the handling of specific Ethernet frames by Cisco IOS XR Software for various Cisco Network Convergence System (NCS) platforms could allow an unauthenticated, adjacent attacker to cause critical priority packets to be dropped, resulting in a denial of service (DoS) condition. This vulnerability is due to incorrect classification of certain types of Ethernet frames that are received on an interface.

2024-09-11 CVE-2024-20483 OS Command Injection vulnerability in Cisco IOS XR
Multiple vulnerabilities in Cisco Routed PON Controller Software, which runs as a docker container on hardware that is supported by Cisco IOS XR Software, could allow an authenticated, remote attacker with Administrator-level privileges on the PON Manager or direct access to the PON Manager MongoDB instance to perform command injection attacks on the PON Controller container and execute arbitrary commands as root. These vulnerabilities are due to insufficient validation of arguments that are passed to specific configuration commands.

7.2
2023-10-10 CVE-2023-44487 The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. 7.5
2023-09-13 CVE-2023-20135 Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Cisco IOS XR
A vulnerability in Cisco IOS XR Software image verification checks could allow an authenticated, local attacker to execute arbitrary code on the underlying operating system. This vulnerability is due to a time-of-check, time-of-use (TOCTOU) race condition when an install query regarding an ISO image is performed during an install operation that uses an ISO image.
